Chapter 413 design of new radar

As at the beginning of the test flight of j-20, this time, the "Falcon" engine of Dongchen in the test flight of j-20 didn't keep secrets deliberately. Moreover, from the striking "Falcon" character in the engine position of the aircraft, we can see that the national test flight of j-20 is actually quite high-profile.

There is no martial law at the test airport, which makes the reporters who receive the wind can take pictures outside the airport arbitrarily, and also record the general dexterous movements of the plane playing in the air in the camera easily. After the photos and videos are spread through the Internet and media, the netizens all over the world begin to discuss and argue about the new j-20. Some people think that the j-20 has already With the most powerful loading capacity in the world in the ranks of fighter planes, with the support of this kind of loading capacity, the new version of j-20 has a great chance to surpass F-22 and become the most powerful fighter in the world. However, some people think that F-22's avionics performance, stealth performance and unparalleled strike performance can not be overtaken by j-20 in any case.

Even the Americans believe that, in their eyes, even if the j-20 has a stronger payload capability, it only enhances the ground attack capability and combat radius of the j-20, but it is absolutely impossible to enhance its survivability when facing the fighter in the air. Although the F-22 lags behind the j-20 in terms of power performance, the most important thing is that the F-22 is not discoverable , and the advantage of preemption.

However, just as the Americans are still looking for a step for themselves, Dongchen once again made a high-profile announcement of an earth shaking event.

That is, Dongchen will develop a new generation of phased array radar!

Radar is like the eye of fighter. In the era when fighter was just born, all air battles rely on sight distance and shooting distance. There is only one way to strike each other, that is to discover first and then strike. However, since the emergence of radar and air-to-air missile, this pattern has changed dramatically. The mode of discovering first and then striking has fallen behind The fighters of all countries are better than those who can first find out the opponents and then take the initiative.

Under the modern air combat pattern, air combat is no longer the era of machine gun sweeping in the sight distance. Now, the air combat really depends on radar sight distance. Moreover, the accuracy of missile is far greater than that of air gun and machine gun, which also means that whoever finds the other party first and launches the missile first is likely to shoot down the other party and protect himself at the same time. His proudest achievement is not his power, but his avionics performance, strike ability and stealth ability. He has achieved the minimum radar reflection surface, which also means that he has the opportunity to hide in the other party's radar for a longer time. Moreover, his powerful avionics performance also ensures that he can find the other party first in the first time before others find himself Under the circumstances, the enemy is generally unable to achieve a real fight with him. Often, the radar has not found the other side, and he has been hit by a missile.

However, if the radar to be developed by Dongchen is far beyond the radar of F22, what kind of situation will it be!

If F22 is greatly weakened in front of Dongchen's radar, what kind of situation will it be!

Modern fighter planes, the protection ability and the strike ability are far from each other. If a strong plane is hit by an ordinary air-to-air missile, it will inevitably face the result of crash. Even if the air-to-air missile of China is not as good as the air-to-air missile of F22, it is enough to eliminate F22.

When Dongchen announced that it was going to develop radar, the whole world felt a hot butt. This time, I'm afraid it's hard to sit still.

the Americans began to evaluate the electronic equipment manufacturing capacity of Dongchen. Based on the current strength of Dongchen, what advantages does Dongchen have in the radar field? The people of E are doing the same thing. The hardest thing is India. They can't sleep at a moment. They are full of thoughts about what kind of weapons the United States can contain the j-20 and j-20 of China Dongchen's radar, what kind of weapon does e have to do this, and how can I get such a weapon.

Dongchen suddenly turned to the national defense industry, which caught the whole world off guard.

At the moment, the domestic high-level is also looking forward to Dongchen. The success of the Falcon engine makes them see the huge potential of Dongchen again. Now, Zhang Yunfeng has taken root in Jiangcheng and started to develop the phased array radar and the three-dimensional navigation satellite of Dongchen.

Xiaoer has a higher pursuit for phased array radar. When designing the R & D plan, Xiaoer said to Zhang Yunfeng, "boss, if we continue to develop phased array radar, the significance is not great."

Zhang Yunfeng was puzzled and asked with a frown, "why is it of little significance? Isn't phased array radar the mainstream radar now? "

Xiaoer nodded and said: "it's true that the mainstream radar is not fake, but this kind of radar has fatal defects. Even if he can track more targets at the same time, the way he detects targets has not changed fundamentally."

Zhang Yunfeng frowned and asked, "what do you mean?"

Xiaoer explained: "you see, the current radar basically uses radar wave as the fundamental means of detection. How does radar wave work? It's an uncontrollable electromagnetic wave. It's like you throw a basin of water out with your eyes closed. If you're not splashed by water, it means that you're not blocked around. If you're splashed by water, it means that there's something around you that blocks the water's path and bounces it back, right? "

Zhang Yunfeng nodded and said, "that's right, and then what?"

? Now the stealth aircraft uses this principle. The radar reflecting surface is very small, and serious refraction occurs when reflecting. In this way, the radar wave projected is like a stone sinking into the sea without information. The operation principle of radar is based on the safety standard of not receiving the reflected radar wave. In this way, it is difficult for the radar to achieve real anti stealth. ”

Zhang Yunfeng couldn't help asking, "what's your best way?"

Xiaoer said with a smile, "the way is very simple. It's to combine it with three-dimensional satellite navigation technology."

Zhang Yunfeng thought for a moment and asked, "do you want to design the radar wave as controllable and measurable as the signal wave of navigation satellite?"

"That's right." Xiaoer said with a smile: "boss, you are really transparent. If we use this technology on radar, then the radar wave is not the water that is thrown out, but the line that is put out. We can detect the whole running route of the radar wave in real time. When it encounters an object, whether it is absorbed or reflected, we can clearly know, the simplest, It is to use the precise ranging of our satellite navigation. If the radar detection distance is 300 kilometers, then the radar wave we send out must be 300 kilometers long. If, through our calculation, some radar waves disappear just when they reach 100 kilometers, then we can conclude that there is an absorbable radar at 100 kilometers If our radar wave doesn't run in a straight line, but turns after refracting like a mirror, we can also detect the specific position of its turning. In this way, the stealth plane will lose its function completely. Whether it absorbs radar wave or refracts radar wave, we can easily detect its existence. "

Zhang Yunfeng was very happy and exclaimed: "this idea is too clever! If the three-dimensional satellite navigation system and radar technology are really combined, the effectiveness of the radar is almost 100%. The existing stealth technology is not enough to fool this intelligent radar. "

"That's right." The waiter nodded his head and said: "in this way, F22 will lose its stealth ability. Moreover, the most important thing is that the radar designed by us has higher power and greater detection distance, which indicates that the aircraft carrying Dongchen radar can find the other side first, and launch the attack first before the other side finds itself."

Zhang Yunfeng couldn't help but say: "this radar technology is absolutely a trump card. Its significance is much greater than that of the Falcon engine. If it is equipped with this radar system, even our J-10 may take the lead in actual combat and shoot down F22. If this radar is ground-based and provides guidance for our air defense missiles, then the whole country The air defense capability of the home will be improved in quality. "

"Yes." Xiaoer nodded and said: "if we really apply this kind of radar to all air combat and air defense fields, I think this kind of air defense system will be the most powerful one in the world. Not to mention that the United States, even the fighters from all over the world, can't escape the radar monitoring. In this way, our air defense missiles will have enough time to lock their eyes And have a strong and stable enough radar as a guide. "

Zhang Yunfeng nods gently. The strength of F22 lies in its excellent stealth performance. It is very difficult for ordinary radar to find him. Even if it finds him, it is impossible to keep tracking. When the angle of F22 changes a little, the radar reflection may be broken. For ordinary air defense missiles, it will take at least seconds or even tens of seconds to lock the target. If the radar cannot When the missile reaches this time, it will not be able to lock the target, or even have the conditions for launching.

However, once the new radar comes out, the whole process of F22 from entering detection distance to driving out detection distance will be mastered by the radar!
