But Feng Yucai suddenly asked at this time:
"But Mr. Zhang, do you think there is anything else hidden on him? Will the enemy attack him suddenly and beat him up now?"
Zhang Desen said:
"General Feng, you can rest assured. In fact, I have already thought about it. I haven't completely asked him some questions. I don't even know the name of their original planet."
General Feng Yucai thought for a moment and said:
"Actually, we don't have to be so confused. Why don't we set up an ambush and catch them all?"
Zhang Desen sighed and said:
"General Feng, sneak attacks and ambushes are certainly good strategies. But the weapons most of us use now are not very advanced. I just pretended that we have a human country with extremely advanced technology, and that scared him. , once he knows the truth, he will probably be very disdainful."
General Feng Yucai thought for a moment and said:
"Mr. Zhang, it seems that everything will be left to you, but what will happen if their people come to attack?"
Zhang Desen thought for a while and said:
"I am in a dilemma about this. In fact, I have told you, General Feng Yucai, how we defeated the Gomar spaceship in the Ulangumu area. But now the problem is, that is, those wandering The base of the aliens. It is not located in the wilderness, but in Hezhou City."
After hearing this, Feng Yucai said:
"No matter what, we must find a way. Otherwise, that base will be our hidden danger."
And Zhang Desen said:
"General Feng must not forget that there is another threat above our heads. Don't forget that huge cigar-shaped space carrier I told you about. It is still hovering in space above our heads. "
General Feng Yucai said:
"In that case, let's just raid their base now. In this case, we can just throw in explosives. Maybe we can directly destroy their base."
And Zhang Desen said:
"It's just that we can't figure out his guards now. By the way, I didn't ask specifically how many people there are in Enba and the others? Are you too anxious today?"
General Feng Yucai said:
"Actually, Mr. Zhang's approach is not wrong. After all, you just asked that in front of too many people. Confidential matters are better handled confidentially. Now that we have time, we can ask again in private."
Zhang Desen said:
"General Feng is right, let's go like this. Let's go down quickly and continue to ask him questions. Find out how many of them there are as soon as possible. However, I want to make it clear that this Emba is not simple. He is probably a senior officer. I am I didn’t expect that he would personally take part in the arrest this time.”
And General Feng Yucai said:
"Actually, this is not surprising. Maybe he doesn't think that I don't have anyone who can arrest him. After all, they are very confident in their technological strength. In fact, when Mr. Zhang asked him this way before, he just wanted to call him He came to help Young Master directly explain some issues, and I can also see that Young Master Zhang just wants me to understand more clearly."
Zhang Desen said:
"So General Feng Yucai, what do you mean now?"
General Feng Yucai said:
"Didn't Mr. Zhang hear their conversation outside their spaceship before? At the same time, Mr. Zhang was also worried that when those accidents happened, he could be made to think that we didn't know the location of their cigar-shaped spaceship, so Zhang I’m right about Young Master’s double insurance plan.”
Zhang Desen couldn't help but admire him and said:
"Yes, since he is indeed a senior officer, I have always been worried that there will be a rescue team that we did not find at any time to rescue him, just to prevent such a thing from happening. So I asked him some repeated questions. Just to prevent him from thinking about it. , I have eavesdropped on their conversation outside their cigar-shaped spaceship. At least they must not think of this."
General Feng Yucai said:
"Then what plan does Mr. Zhang have to destroy the cigar-shaped mothership in space?"
Zhang Desen said:
"General Feng, it's too public here. Although you have already asked your men to go far away. I also want some people to go far away. Why not go to the airport, maybe something will happen soon."
At this moment, a guard suddenly came over and reported:
"Report Captain. The radar on our Crater discovered that the huge cigar-shaped space carrier sent a small spacecraft into the atmosphere of our planet. I don’t know if it’s because of the error in calculation accuracy or some other reason? The opponent will enter the sky over Hefei soon. Our radar and anti-aircraft firepower can fire at any time. "
Zhang Desen said:
"Okay, let's talk about it when I get back."
Afterwards, Zhang Desen walked back to the airport and entered the "Crater" with those who could be allowed to enter the "Crater". Of course, Zhang Desen and others have not forgotten Wang Jia. At this time, Wang Jia had been taken back to the rest area of the Liujia Commercial Bank branch outside the city. Of course, it was impossible for him to see Liujia Airport. After all, Zhang Desen still has some doubts about him.
However, what Zhang Desen must face at this time is the alien spacecraft in the sky. It was at this time that the radar operator reported:
"Report to the captain, the enemy plane has left the sky over Hefei and is flying towards the vicinity of Hezhou City at a very fast speed."
Zhang Desen then said:
"Okay, keep holding on and don't relax for a second."
The radar announcer immediately replied:
"yes!"
Afterwards, everyone continued to track the movements of the enemy spacecraft through radar. However, just when everyone thought he would fly directly to Hezhou City, the UFO flew north to Bengbu for some unknown reason.
The radar announcer also immediately reported to Zhang Desen. After hearing this, Zhang Desen asked him to continue to use radar tracking and surveillance. At this moment, Zhao Chengming said:
"Captain, based on the information you heard from the cigar-shaped UFO before, the enemy is not actually arresting slaves only in Hezhou City. Could they be planning to capture slaves in Bengbu or Bengbu this time? What about the captured spacecraft elsewhere? Do we need to track them immediately?"
Zhang Desen thought for a while and then said:
"Wait a minute, let's continue to monitor him. I'm a little interested in the purpose of his visit this time."
However, not long after, the UFO suddenly changed its direction and flew towards Xidu. This time, Li Longfang and Zhao Chengming suddenly became anxious. Because there is a joint industrial park near Xidu, they are worried that if these are completely exposed, they will be in big trouble. In addition, their family is also in the Western Capital City area.
In fact, Zhang Desen is also a little worried, because what he hates most is the sudden appearance of these potential enemy threats in his rear. Therefore, Zhang Desen asked the liaison officer to immediately contact the drug direction. As long as the enemy's UFO suddenly appeared near Xidu, as long as it entered the range of the anti-aircraft firepower, the United Industrial Park area.
However, it seems that Zhang Desen and the others are a little too worried. Because the UFO in the sky suddenly changed its direction and flew towards Jiangning.
At this time, everyone was a little confused. They didn't expect this UFO to fly around randomly like this, and they couldn't figure out what the enemy was doing. At this time, Zhao Chengming said again:
"Captain, I think the enemy seems to have another purpose. Such random analysis by the enemy seems a bit too baffling and inconsistent with common sense. But I think their target is still here in Hezhou City. Otherwise, they should simply go to other places. It’s the right direction to fly.”
Zhang Desen said at this time:
"What do you think, but no matter what, I'm a little impatient with this hide-and-seek game. After a while, they approached Hezhou City and shot down the enemy plane directly."
Zhao Chengming immediately replied:
"clear."
However, Zhang Desen still plans to direct it himself. Soon, this UFO finally approached the sky above Hezhou City. I have to say that this spaceship flies really fast.
Subsequently, the radar announcer immediately reported to Zhang Desen:
"Captain, the enemy has reached the sky above Hezhou City. Do you want to lock the radar?"
Zhang Desen immediately made up his mind and said:
"Okay, I can lock the target."
Soon, radar broadcast
The reporter immediately said:
"The target has been completely locked."
Zhang Desen said immediately:
"Very good, three missiles are powered on."
The missile launcher immediately reported:
"Three missiles have been successfully powered on."
After hearing this, Zhang Desen immediately said:
"Okay, three missiles, attack the target."
Then three missiles quickly flew towards the target, but this UFO didn't know if it was because it had been on Earth for a long time, and it had no air defense resistance, so it didn't realize that any target would attack it. At this time, it was still accelerating towards the sky above Hezhou City.
However, just when the operator on board the UFO reacted. Suddenly a missile hit the UFO, and then the remaining two missiles hit it one after another.
These missiles are missiles left behind by super-ancient humans, and they can still deal with some ordinary alien spacecraft. Soon the UFO disintegrated in the air and finally fell to the ground.
Of course, the joint team outside quickly dispatched and tried their best to collect the wreckage at the crash site so that they could collect the science and technology above for their own use.
But General Feng Yucai, his curiosity arose again at this time, and asked Zhang Desen:
"Well, what did Mr. Zhang just have?"
Zhang Desen immediately answered him and said:
"They are surface-to-air missiles among missile weapons. Although relatively speaking, these missiles left by super-ancient humans can hit even ordinary UFOs. But they still belong to the category of surface-to-air missiles."
Then, Zhang Desen quickly told General Feng Yucai some information about surface-to-air missiles.
Surface-to-air missiles refer to missiles launched from the ground to attack air targets. Also known as anti-aircraft missiles. It is the core of the surface-to-air missile weapon system.
Surface-to-air missiles are a type of missile weapon launched from the ground to attack enemy aircraft, missiles and other air targets. They are an important component of modern air defense weapon systems. Compared with anti-aircraft guns, it has a long range, a high shot, and a high single-shot hit rate;
Compared with interceptors, it has fast reaction speed, fierce firepower and great power. It is not limited by target speed and altitude. It can form a tight air defense firepower network at high, medium and low altitudes and at long, medium and short ranges.
The kinematic relationship based on which the surface-to-air missile guidance system guides the missile to fly to the target is called the guidance law, also known as the guidance method. The guidance law describes the movement law followed by the missile during the entire process of approaching the target. It determines the ballistic characteristics of the missile and its corresponding ballistic parameters.
Under the given conditions of target movement law, missile flight speed change law and guidance method, using the missile as a controllable mass point, the trajectory of the missile flying to the target is determined, which is called the ideal trajectory. Obviously, the guidance methods are different, the ballistic parameters and motion parameters of the flight are different, and the ideal ballistic shape is also different.
There are various guidance laws for surface-to-air missiles. According to the research methods, some are based on the concepts of early classical theories, and some are based on modern control theory and countermeasure theory. Guidance laws based on concepts from early classical theories are often called classical guidance laws.
Classic guidance laws mainly include the three-point method, the front method or the half-front method, the speed tracking method, the attitude tracking method, the parallel approach method, the proportional guidance method, etc. The most commonly used are the three-point method and the half-front method. and proportional guidance method and its improved form. The classical guidance law requires a small amount of information, has a simple structure, and is easy to implement. Therefore, most surface-to-air missiles currently in service still use the classical guidance law or its improved form.
The guidance law based on modern control theory and game theory is usually called modern guidance law. The modern guidance laws studied in surface-to-air missiles using modern control theory and countermeasure theory mainly include linear quadratic optimal guidance laws, white adaptive guidance laws, differential strategy guidance laws, etc.
With the different selection of performance indicators, their forms are also different. The performance indicators considered in modern guidance rules are mainly the minimum total overload required by the missile during flight, the minimum terminal miss, and specific requirements for the intersection angle between the missile and the target.
However, because missile guidance is inherently a nonlinear problem with variable parameters and subject to random interference, it is difficult to achieve accurate optimal guidance, so it is usually only
It is best to make a linear assumption about the process of missile intercepting the target. An approximate solution is obtained. This guidance law is easy to implement in engineering and is close to the optimal guidance law in performance.
The modern guidance law has many advantages over the classic guidance law, such as small miss distance, satisfactory attitude angle when the missile hits the target, strong ability to resist target maneuvers or other random interference, straight ballistic trajectory, and reasonable overload distribution for the ballistic trajectory. Expansion of combat airspace, etc.
Therefore, using modern guidance
It is effective to guide missiles to intercept high-speed, large-maneuvering, and interference-capable targets that will appear on future battlefields; however, its structure is complex and requires many measurement parameters, resulting in greater challenges in the realization of guidance laws. difficulty.
With the improvement of automation and informatization of surface-to-air missile weapon systems and changes in measurement and calculation methods, the application of modern guidance laws can be realized.
A method for the surface-to-air missile target search and tracking system to observe target spatial coordinates and motion parameters. One of the elements of the SAM firing method. There are usually manual tracking, semi-automatic tracking, automatic tracking and hybrid tracking. Correct selection of tracking methods can improve the accuracy of the tracking system in measuring target spatial coordinates and motion parameters.
The selection of tracking methods is flexibly used by the commander based on factors such as air targets, interference and anti-jamming conditions, and the performance of tracking equipment. When using manual tracking, the tracker continuously controls the equipment to make the observation mark coincide with the target signal.
When using semi-automatic tracking, the tracker continuously sets the motion parameters of the target mark, and then the tracking equipment automatically aligns the observation mark with the target signal.
When using automatic tracking, the tracking equipment automatically aligns the observation mark with the target signal. When using hybrid tracking, some of the branches such as elevation angle, azimuth angle, and distance are automatic or semi-automatic tracking, and some are manual tracking.
That's it. Zhang Desen probably introduced the information about surface-to-air missiles to Feng Yucai, but he didn't have much time, so he had to continue doing what he should do.
General Feng Yucai said at this time:
"So Mr. Zhang, what should we do now? I think our army has also brought a lot of artillery. I think no matter how good other people's science and technology are, using artillery to directly destroy that base disguised as an ordinary civilian house should be It can be done, what do you think?"
However, what General Feng Yucai said really gave Zhang Desen a big reminder, and Zhang Desen suddenly thought. He couldn't help but say:
"My true love, General Feng is indeed a veteran on the battlefield. General Feng reminded me. If we directly bombard that house with artillery fire, then the camouflage layer on it will inevitably fall off."
Then, Zhang Desen breathed a sigh of relief and continued:
"And that house was indeed just an ordinary residence originally. It was only after being bought by those alien civilizations that some modifications were made secretly. But no matter how modified it was, it was still essentially a house built by humans. When our artillery blasted that house After the house was destroyed, those aliens could only use their vehicles to escape. Then, hum..."
Zhao Chengming continued:
"If they're trying to escape in their vehicle, then all the firepower we have aboard the Crater is not going to happen." Then, we will eliminate them all on our planet one by one, and make them never come back. Then, use a nuclear strike against the huge cigar-shaped space carrier in space to destroy it. "
Hearing what Zhao Chengming said, Zhang Desen was suddenly stunned. Only then did he remember that when he was talking about the different powers of nuclear weapons when used in the atmosphere and in space, he had only told Li Longfang, and Zhao Chengming and the others didn't know about it yet.
Then, Zhang Desen looked around and saw people who could know the secret. Zhang Desen had no choice but to tell again what he had told only to Li Rongfang that time. The general content is:
In fact, there is a big difference in the power of a nuclear strike in the atmosphere and in airless space, mainly in terms of radiation, shock waves, etc.
And when a nuclear weapon explodes in the atmosphere, the atmosphere in the atmosphere will amplify the shock wave of the nuclear explosion. Therefore, the shock wave when a nuclear weapon explodes in the atmosphere is very huge.
At the same time, the surrounding air will also fully diffuse the thermal energy radiation emitted when it explodes, making it
The lethality can be said to have increased exponentially.
However, the atmosphere in the atmosphere will also quickly absorb the nuclear radiation produced by its nuclear explosion. Therefore, the radiation produced by a nuclear weapon exploded in the atmosphere is far lower than the nuclear radiation produced in space.
However, if a nuclear weapon explodes in space, there is no atmosphere in space to amplify the shock wave for the exploding nuclear weapon. Of course, there is no atmosphere in the atmosphere to absorb other shock waves generated when it explodes. Therefore, the power of almost all shock waves caused by a nuclear weapon exploding in space is far weaker than the power of the shock wave it generates in the atmosphere.
However, it is also because there is no atmosphere in the atmosphere for the nuclear weapon to explode to absorb the nuclear radiation it produces when it explodes. Therefore, the nuclear radiation produced when a nuclear weapon explodes in space is much higher than that of a nuclear weapon exploding in space. The nuclear radiation is about ten times greater.
Therefore, when a space warship operating in space encounters a nuclear explosion in space, the power of the nuclear shock wave it has to fight against will be far weaker than the power it has to fight in the atmosphere.
When a space warship travels in space, it needs to prevent many types of impacts in space, including unexpected impacts such as asteroids, so it must be extremely strong.
Then, when a nuclear weapon has a big explosion around it, it does not have to bear such a huge nuclear explosion shock wave in space. At least such a shock wave is definitely far weaker than the shock wave in the atmosphere, so it It is very likely to withstand the explosive power of a nuclear bomb.
In other words, the explosion of a nuclear weapon in space may have a different impact on a spacecraft. It was very easy to push through, but it was different in the atmosphere.
Although, the nuclear radiation produced when a nuclear weapon explodes in space will be far weaker than that in the atmosphere. However, there is a lot of terrifying space radiation in space. Therefore, when any spacecraft is manufactured, it must have a very good radiation protection design to ensure the safety of the people inside the ship.
Therefore, although the nuclear radiation produced by the explosion of nuclear weapons in space is ten times that in the atmosphere, it is also different for space vehicles.
That is, the reasons mentioned above. Therefore, if Zhang Desen and the others carry out a nuclear attack on the Gomar space battleship "Bingliang" at that time, if they are in space, they may not be able to cause any real impact on the Gomar people's "Bingliang" space battleship. threats. The same goes for other spaceships.
After listening to Zhang Desen's story, Zhao Chengming couldn't help but become a little nervous, so he had to ask:
"Then what should we do, Captain?"
Zhang Desen smiled and then said:
"What else can we do? Of course we go directly to Mars. And we have to do it before the Gomar troops arrive. Completely solve the Mars problem."
After everyone heard this, they all fell silent immediately, because they knew that Zhang Desen had not finished speaking yet, and they were all waiting for him to finish.
