If you look at the side, draw a 45 degree extension line upward on the nose of MiG-29. If it is an ordinary semi-active radar, it will dive down to face the attack. It must be below the extension line and will be found by the radar. However, thunderbolt-12 is not staring at the target at all. It is still a high-altitude trajectory, just above the extension line, Outside of the electromagnetic wave cone! At this time, the electromagnetic wave has collided with the body of J-11B.

If it is the previous J-11, the huge body has reflected a large number of electromagnetic waves back, which is enough to form a clear bright spot on the radar screen of MIG 29.

However, j-11-b is not. The nose of this fighter has a rhombic cross-section. When the radar beam shines up, it does need to reflect, but according to the law of reflection, it will never return the same way. That is a phenomenon only when it is incident at 90 degrees vertically. Now, it collides with the nose of j-11-b at a large angle and reflects away at a large angle. It is already facing both sides!

The stealth coating of the nose absorbs another part, and only a small part of the radar beam can be reflected back.

Neither the nose nor the fuselage. The shape of the fuselage is the same. Most of them are reflected on both sides. The joints are strongly reflected, but the joints are sawtooth, and the clutter in all directions is reflected back.

Finally, it can reflect back and enter the echo of MIG 29 nose radar, less than one thousandth. This beam is directly filtered out as clutter in the radar's internal processor, without any response.

If the Su-27 radar has a large caliber and a much larger detection distance, or if the phased array radar gathers all the beams, it may be able to find the current J-11B. However, relying on the MiG-29 radar, the detection distance will not exceed 20 kilometers. At a distance of 20 kilometers, it is enough to visually find the target, In particular, the current fuselage of J-11B is painted in black, which is still relatively clear in the blue sky.

If the missile on the belly of the aircraft is not launched, there will still be a lot of clutter formed by the missile. However, now that the missile has been launched, the remaining conformal pylons are perfectly integrated with the fuselage to form an invisible shape.

Without finding the target, it seems that they have to continue to fly forward, fly dozens of kilometers, and then search. Deng Wenlin turned off the radar. The radar can't be used for a long time, otherwise they will expose their own targets.

In fact, even if they pass by the Han fighters, they won't be afraid. Instead, it will be better. They can climb from the sea at an ultra-low altitude, fly to the back of the Han fleet and fire at them. That's the best time.

Thinking of this, Deng Wenlin raised his head and looked at the sky. When flying MIG 21, there was no airborne radar at all. He mainly depended on his sharp eyes to find the target. Therefore, he looked up at the sky from time to time, hoping to visually search the target from the sky. Today's weather is quite good, and he even felt that, I may be able to find the target 30 or 40 kilometers away.

In the sky, there are white clouds floating. At a higher height, it seems that there are so many leucorrhea. Leucorrhea is slowly spreading. It looks strange. What is that?

Deng Wenlin's brain hesitated.

This kind of leucorrhea gradually spreads, of course, like the wake of a fighter in the air. However, he didn't see a fighter in front of the leucorrhea, so he didn't think it was a fighter flying. If it wasn't a fighter, what was it?

He was a little curious, and then looked at the past, the leucorrhea did not continue to extend, but just began to spread.

He controlled his thoughts. He'd better concentrate on finding his goal.

Of course he didn't know. He missed his last chance.

Ordinary missiles use solid rocket motors. When they are ignited and launched, there must be wakes, but the intensity of the wakes is different. However, one of the characteristics of rocket motors is that the combustion time will not be too long. The same is true for current air-to-air missiles. During the initial launch period, the engine ignites and drives the missile to accelerate, but then, After the fuel of the missile is burned, the rest of the time is to fly by inertia. Even if the power engineers use various methods to slow down the combustion of the solid motor, it will take only a few tens of seconds at most.

The overload of the missile is often dozens of g. in fact, it means the stage with power. After there is no power, only relying on inertia, the speed will be slower and slower, and the mobility will be weaker and weaker.

If a semi-active missile keeps turning with the target, its energy will be continuously consumed. However, the active missile is different. It does not need to stare at the target all the time. Now it flies smoothly at high altitude, which saves energy most.

Moreover, now it has completed the stage of horizontal flight and began to dive downward. When diving, the gravitational potential energy is converted into kinetic energy, and the mobility will increase!

During the dive, the warhead's active radar seeker began to work.

Although it is called an active radar missile, it doesn't matter what it says after launch. In fact, limited by the volume of the seeker, the action distance will not be too far, that is, between 10 km and 20 km. Before, it still needs guidance, otherwise, the target may be lost.

Of course, it's not afraid to lose it. It can also choose other targets to attack, as long as it can see it.

Therefore, on the battlefield, if you use active missiles, you may be timid. For example, your comrades in arms are fighting with enemy aircraft and you want to use medium-range missiles to help. At this time, the active missiles are unreliable. Although the enemy aircraft are locked, in the past, they are likely to catch up with your comrades in arms, but semi-active ones are more reliable, The whole process is in the hands of the fighter. Once something bad is found, stop irradiation, the missile will unlock, and the initiative will not work.

Now, after the missile goes down, it just brings those aircraft groups into the range of the seeker. The seeker finds the target assigned to itself in advance according to the guidance of the data link, and then starts to launch a thin monopulse radar beam and turn into the locked state.

"Drop, drop, drop." MIG 29's siren-10 radar alarm receiver was immediately activated and sent out an audible alarm signal.

From this moment on, MIG 29 found that it had been locked, but where was the enemy?

If the radar warning receiver is omni-directional, they may be able to know that the missile is hitting from above. At this time, the missile is diving, but it is not. At the moment they find it locked, they are nervously searching for where the attacking aircraft comes from. They originally came for a sneak attack, but now, they are actually attacked?
