Just like when the J-20 first started the test flight, this time, the J-20 test flight of the Dongchen "Falcon" engine did not deliberately keep it secret, and it can be seen from the eye-catching "Falcon" word on the aircraft engine position that the country's test flight of the J-20 this time is actually quite high-profile.

There is no martial law at the test airport, which allows reporters who receive the news to shoot outside the airport, and also easily record the dexterous movements of the plane in the air in the air, after the photos and videos are disseminated through the Internet and the media, netizens all over the world have begun to discuss and argue around the new J-20, some people believe that the J-20 has the world's most powerful load capacity in the ranks of fighters, with the support of this load capacity, the new facelift of the J-20, There is a great chance to surpass the F-22 and become the most powerful fighter in the world, however, some people believe that the F-22's avionics performance, stealth performance and unparalleled strike performance are impossible for the J-20 to catch up with no matter what.

Even the Americans think so, in their eyes, even if the J-20 has a more powerful load capacity, it only enhances the ground attack capability and combat radius of the J-20, but it is absolutely impossible to enhance its survivability in the air in the face of fighters, although the F-22 is a big step behind the J-20 in terms of power performance, but the most important thing is that the F-22 is undiscoverable, and the advantage of preemptive strike.

However, just when the Americans were still looking for a step for themselves, Dongchen once again announced an earth-shattering event in a high-profile manner.

That's it. Dongchen is going to develop a new generation of phased array radar!

Radar is like the eyes of a fighter jet, in the era when fighter jets were just born, all air combat relied on the distance of sight and shooting distance, and there was only one means to hit the other side, that is, to discover first, and then strike. However, since the advent of radar and air-to-air missiles, this pattern has begun to change dramatically, and the pattern of first detection and then strike has become backward, and the fighter jets of various countries are competing with who can detect the opponent one step ahead and then strike first.

Under the modern air combat pattern. Air combat is no longer the era of machine gun sweep within visual range, and the current air combat is really fought, relying on radar visual range, and the accuracy of missiles is far greater than that of aircraft guns and machine guns, which also means. Whoever discovers the opponent first and launches the missile first is likely to shoot down the opponent while preserving himself.

The F-22's proudest achievement is not his motivation. It's his avionics performance and strike capabilities and stealth capabilities, he has achieved the smallest radar reflective surface, which also means that he has the opportunity to lurk in the opponent's radar for a longer time, and. His strong avionics also ensures that he can be the first to be seen, before others have even discovered him. In this case, the enemy is generally unable to achieve a real battle with him at all, and often the radar has not yet detected the opponent, and he has already been hit by a missile.

However, if the radar that Dongchen is about to develop far exceeds the radar of the F-22. What would that look like?!

If the F-22 is in front of Dongchen's radar, the stealth capability will be greatly weakened. What would that look like?!

Modern fighters, the ability to protect and strike is far from the ability to strike, no matter how strong the aircraft, if it is hit by an ordinary air-to-air missile, it will inevitably face the result of crashing, even if China's air-to-air missiles are not as good as the F-22 carried by the anti-air missile, but the elimination of the F-22 is enough.

When Dongchen announced that it was going to develop radar, the whole world felt a burst of heat in the butt, and this time, I am afraid it will be difficult to continue to sit still.

The Americans began to evaluate Dongchen's electronic equipment manufacturing capabilities, analyzing the current strength of Dongchen, what kind of strengths Dongchen has in the field of radar, the Russians are also doing the same thing, the most bitter is India, they can't sleep all of a sudden, all of a sudden they are thinking about what kind of weapons the United States has to contain China's J-20 and Dongchen's radar, what kind of weapons Russia has to do this, and then how can they get such weapons.

Dongchen's sudden turn to the defense industry caught the world off guard.

The success of the "Falcon" engine has made them see the huge potential of Dongchen again, and now, Zhang Wenhao has taken root in Jiangcheng and began to develop Dongchen's phased array radar and stereo navigation satellites.

Xiao Er has a higher pursuit of phased array radar, and when designing the research and development plan, Xiao Er said to Zhang Wenhao: "Boss, if we continue to develop phased array radar, it is no longer of much significance." ”

Zhang Wenhao was puzzled, frowned and asked, "Why is it meaningless?" Isn't phased array radar the mainstream radar now? ”

Xiao Er nodded and said: "It is true that the current mainstream radar is true, but this kind of radar has fatal flaws, even if he can track more targets at the same time, his way of detecting targets has not changed fundamentally." ”

Zhang Wenhao frowned and asked, "What do you mean?" ”

Xiao Er explained: "You see, the current radar basically uses radar waves as the fundamental means of detection, how do radar waves work? It's a kind of electromagnetic wave that is uncontrollable, it's like you are splashing a basin of water with your eyes closed, if you are not splashed by water, it means that there is no obstruction around you, once you are splashed by water, it means that there is something around you that blocks the path of the water and bounces back the water, right? ”

Zhang Wenhao nodded and said, "That's right, then what?" ”

Xiao Er smiled: "Then the problem arises, the water that is splashed out, the same as the radar wave released, we can't control it ourselves, the radar wave touches the object and reflects back, so that the radar can distinguish the other party, if the radar wave is absorbed or interfered with and refracted, and no longer returns, then the radar will not be useful?" The current stealth aircraft uses this principle, the radar reflection surface is very small, and serious refraction will occur when reflected, so that the radar wave projected out is like a stone sinking into the sea without information, and the operating principle of the radar is to not receive the reflected radar wave as the safety benchmark, so that it is difficult for the radar to achieve real anti-concealment. ”

Zhang Wenhao couldn't help asking, "Then what good way do you have?" ”

Xiao Er smiled: "The solution is very simple, that is, to combine it with stereoscopic satellite navigation technology." ”

Zhang Wenhao pondered for a moment and asked, "Do you want to design radar waves to be controllable and measurable like the signal waves of navigation satellites?" ”

"That's right." Xiao Er smiled: "Boss, you are really thorough, if we use this technology on the radar, then, the radar wave that goes out is not the water that is splashed out, but the line that is released, we can detect the entire running route of the radar wave in real time, it encounters the object, whether it is absorbed or reflected back, we can all know clearly, the simplest, is to use the accurate ranging of our satellite navigation, if the radar detection distance is 300 kilometers, If, after our calculations, some radar waves are disappeared when they have just reached a length of 100 kilometers, then we can conclude that at a position of 100 kilometers, there are objects that can absorb radar waves, and if our radar waves do not operate in a straight line, but turn after refraction similar to a mirror, we can also detect the specific position of their turning, so that the stealth aircraft will completely lose its effect. Whether he absorbs or refracts radar waves, we can easily detect their presence. ”

Zhang Wenhao was overjoyed in his heart, and exclaimed: "This idea is too smart!" If the stereoscopic satellite navigation system and radar technology are really combined, then the effectiveness of the radar will reach almost 100%, and the existing stealth technology is not enough to deceive this intelligent radar. ”

"That's right." Xiao Er nodded again and again, and said: "In this way, the F-22 has completely lost its stealth specialty, and, most importantly, the radar we designed has higher power and greater detection range, which also indicates that the aircraft equipped with Dongchen radar can detect the other party first, and take the lead in attacking when the other party has not yet discovered itself." ”

Zhang Wenhao couldn't help but speak: "This kind of radar technology, absolutely killer general existence, its significance, is far greater than the" falcon "engine, if equipped with this radar system, even our J-10, it is possible to preemptively shoot down the F-22 in actual combat, if this radar is grounded, to provide guidance for our air defense missiles, then the entire country's air defense capability will be qualitatively improved." ”

"yes." Xiao Er nodded and said: "If we really apply this kind of radar to all the fields of air combat and air defense, I think this air defense system will be the most powerful one in the world, not to mention the United States, even if the world's fighter jets come one by one, they will not be able to evade the radar monitoring, in this way, our air defense missiles will have enough time to lock on to the target, and have a strong enough and stable radar as a guide." ”

Zhang Wenhao nodded lightly, the strength of the F-22 lies in his stealth performance is too good, the general radar is not only extremely difficult to find him, even if he is found, it is impossible to keep tracking, the F-22 angle changes slightly, the radar reflection wave may be cut off, and the general air defense missile, it takes at least a few seconds or even more than ten seconds to lock on to the object, if the radar can not buy this time for the missile, then the missile can not lock the target at all, can not lock the target, and even does not have the conditions for launching.

However, once this new radar comes out, the F-22 will be in the radar's hands from entering the detection distance to driving out of the detection distance! (To be continued.) )
