Chapter 2342: Missile arrival

If you look at the side, draw a 45-degree extension line on the nose of the MiG-29. If it is an ordinary semi-active radar, you have to dive down to face the attack. It must be below this extension line and it will be detected by the radar. But the Pili-12 is not staring at the target at all now, and it is still walking a high-altitude ballistic, just above this extension line, outside of the electromagnetic wave cone! At this time, the electromagnetic wave had already hit the body of the F-11B.
If it were the previous J-11, then the huge body has already reflected a lot of electromagnetic waves back, enough to form a clear bright spot on the MiG-29 radar screen.
But this is not the case with the F-11 B. The nose of this fighter has a diamond-shaped cross-section. When the radar beam is irradiated, it does reflect, but according to the law of reflection, it will never return the same way, which is 90 degrees vertical. It is a phenomenon that can only occur when it is incident. Now, it slammed into the nose of the F-11 B at a large angle, and reflected away at a large angle, already facing both sides!
The stealth coating of the nose absorbs a part, and only a negligible part of the radar beam can be reflected back.
The nose is not good, and the fuselage is not good. The shape of the fuselage is also the same. Most of it is reflected to the sides. The seams are originally reflected strongly, but the seams are all jagged. Processing, the clutter in all directions is reflected back.
In the end, it can be reflected back and enter the echo of the MiG-29 nose radar, which is less than one-thousandth. This beam is directly filtered as clutter in the internal processor of the radar, and there is nothing. reaction.
If it is a Su-27 radar, which has a larger caliber and a much longer detection distance, or a phased array radar, which converges all the beams, it may be able to find the current F-11 B, but it depends on the MiG-29. Radar, the discovery distance will not exceed 20 kilometers, at a distance of 20 kilometers, it is enough to detect the target visually, especially the current body of the F-11 B is painted in black, and it is still in the blue sky. Relatively clear.
If the missile on the belly is not launched, there will still be a lot of clutter formed by the missile, but now, the missile has been launched, and the remaining conformal pylons are perfectly integrated with the fuselage to form a stealth shape.
No target was found. It seemed that they had to continue to fly forward, fly several tens of kilometers, and then search again. Deng Wenlin turned off the radar. The radar could not be used for a long time, otherwise their own targets would be exposed.
In fact, even if they pass by the Han fighters, they will not be afraid. That would be better. They can climb from the sea at a super low altitude, fly to the back of the Han fighters, and fire at them. The best time to plant.
Thinking of this, Deng Wenlin raised his head and looked at the sky. When he was flying MiG 21, there was no airborne radar at all. To find the target, he mainly relied on his sharp eyes. Therefore, he looked up from time to time. In the sky, I hope to find the target visually from the sky. Today's weather is quite good. He even felt that he might be able to find the target thirty or forty kilometers away.
In the sky, there are white clouds floating in the sky. At higher altitudes, it seems that there are so many leucorrhea, and the leucorrhea is slowly spreading. It looks strange, what is it?
Deng Wenlin's brain hesitated.
This kind of leucorrhea gradually spread. Of course, it looked like the wake of a high-altitude fighter jet. However, he did not see that there was a fighter in front of the leucorrhea, so he didn't think it was a fighter flying. If it was not a fighter, what would it be? ?
He was a little curious, and then when he looked over, the leucorrhea did not continue to extend, it just started to spread.
He controlled his thoughts, so he should concentrate on finding his goal.
Of course he didn't know, he missed the last chance.
Ordinary missiles use solid rocket motors. When it is ignited and launched, there must be a trail, but the wake is different in intensity. However, a feature of rocket motors is that the combustion time is not too long. The same is true for current air-to-air missiles. During the first period of launch, the engine ignites and accelerates the missile. But then, the fuel of the missile is burned, and the remaining time is to fly by inertia, even if the power engineers use various The method to slow down the combustion of a solid engine is only a few tens of seconds at most.
The missile's overload is often dozens of Gs. In fact, it refers to the power stage. After there is no power, relying only on inertia, the speed will become slower and slower and the mobility will become weaker and weaker.
Semi-active missiles have to keep turning with the target, and energy will continue to be consumed. Active missiles are different. They don't need to keep staring at the target. They fly smoothly at high altitude and save energy most.
Moreover, now it has completed the horizontal flight stage and has begun to dive down. When it dives, the gravitational potential energy is converted into kinetic energy, and its mobility will increase!
As it dived, the active radar seeker of the warhead began to work.
Although it is called an active radar missile, you don’t need to worry about it after launching. In fact, limited by the volume of the seeker, the range of action will not be too far, that is, between 10 kilometers and 20 kilometers. Guided, otherwise, the target may be lost.
Of course, you are not afraid of losing it. It can also choose other targets to attack, as long as it can see.
Therefore, on the battlefield, if you use active missiles, you may shrink your feet. For example, your comrades are fighting with enemy aircraft and you want to use medium-range missiles to help. At this time, active missiles are not reliable, although they are locked. The enemy plane, but passed by, is likely to chase one's comrades in flight. On the contrary, it is semi-active and more reliable. The whole process is controlled by the fighter. Once you find something wrong, stop the irradiation, the missile will be unlocked, and the active will not work Up.
Now, after the missile descends, it happens to include those fleets within the range of the seeker. According to the guidance of the data link, the seeker finds the target assigned to it in advance, and then starts to launch a thin single pulse. The radar beam turned into a locked state.
"Di, di, di." The siren-10 radar warning receiver of the MiG-29 was immediately activated and issued an audible warning signal.
From this moment, the MiG-29 fleet realized that it had been locked, but where was the enemy?
If the radar warning receiver is omnidirectional, they may be able to know that the missile was shot from overhead, and the missile is diving at this time, but it is not. They were nervously searching for the attack the moment they found it was locked. Where did his plane come from? They were originally attacked, but now they have been attacked?
