Super Weapon Swap System

To be precise, this was not the weakness of the Male Cat Fighter, but the common weakness of all the Doppler radars.    

The working principle of the Doppler radars was not complicated. When the radars sent out a fixed frequency of pulse waves to scan the air, if the Doppler radars encountered a moving target, the frequency of the pulse wave's return and the frequency of the launch wave would be different. It was called the Doppler frequency.    

If it was a fixed target on the ground, then it was a confirmation value. In the radar processing system, it could be removed.    

What was the benefit of this?    

Before the pulse Doppler radar appeared, an ordinary single-pulse radar... They couldn't detect low-altitude targets because there were so many ups and downs on the ground. Various buildings and so on were reflecting radar waves on the radar screen. It was definitely a snowflake.    

Only by filtering out the signals on the ground could they accurately find the target. This way, they would be able to find the planes that were trying to use the terrain as cover.    

This principle was very roundabout. If one took a train, the moment the two trains met, or on the platform, they could watch the train enter the station and hear the train's whistle.    

Originally, the train had come all the way from a distance, but when it got close, the sound would change. The sound would become higher, and this was the Doppler phenomenon. It was because when the train passed through, the frequency of the sound changed.    

After talking for a long time, the Pulse Doppler radar was very powerful. However, it was also flawed, sometimes leaving out the target. For example, he couldn't discover it, nor could he attack an enemy aircraft that was flying at the same speed as him. At the same time, he couldn't attack a target that was vertical to his own aircraft. At this moment, the target was the same as the stationary target. It was filtered out.    

At this time, it had to be converted into PSTT mode, single-pulse mode. Without the Doppler function, it wouldn't be filtered out.    

However, this required time.    

At the same time as Cross in the rear cabin changed, Chen Rui had already flown out of the cloud.    

Just now, he was inside the cloud. When the simple radar-warning receiver on MiG 21 discovered that there was radar scanning, he flew out. At the same time, he flew in a vertical direction with the other party.    

As a result, the other party was unable to lock onto Chen Rui.    

This was a commonly used tactic in aerial warfare. However, it absolutely required the pilot's superb skills because they had to perfectly fly vertically. This was completely the pilot's instinctive reaction.    

However, this also meant that MiG 21 was gradually distancing himself from the opponent. How could he get close?    

Of course, he would spin half a circle before flying backwards.    

Just like in the ancient era of sailboats, wouldn't sailboats only be able to sail with the wind? Of course not, for experienced old sailors, they could totally steal the sailing boats. At this time, the boat absolutely did not walk towards the wind, but rather took a zigzag route back and forth. Then they could go against the wind.    

Now, after turning half a circle, the direction was still the same. And... The other side's route was still vertical, but the distance was getting closer. They kept flying back and forth like this, forming an S shape. It was also called the snake turn. This technique, in the old hands... It was very valuable.    

In the future, there were backward planes that relied on this kind of maneuvering to break through the Eagle people's pride of long-range defense and directly charge in front of them.    

The current Chen Rui was like this. He made a snake-shaped turn and successfully killed his way in front of the enemy.    

If your sword is not long enough, then take a step forward! Even in this era, flying daggers are still useful. When your plane is not advanced enough, use tactics to make up for it!    

In the tower, the Eagle people gradually became silent from their shock. They looked at the status on the screen and saw Chen Rui charging towards the male cat with a fearless spirit. Their feelings were complicated.    

Up until now, the male cat fighter had been suppressed. They did not even have the chance to turn the radar into the PSTT and lock onto it again. They were already in front of it!    

Even if the male cat could lock onto the opponent in the end, it would still be a glorious defeat for the MiG 21. Up until now, the male cat did not have the upper hand. That was already a defeat.    

Han Country was a terrifying country, their pilot. Everyone was not afraid of death! Back in Korea, they were like this. The newly born Han Country Air Force had already made the trump card of the Y Country, the Air Force-navy, tremble in fear.    

Such an Air Force was worthy of respect.    

It was useless to flatter others. Only by using his powerful strength to prove himself would he be able to win the respect of others, just like now.    

As for General Zhang, he was already grinning from ear to ear.    

As long as he was not immediately locked down and killed, Chen Rui would have given face to the Air Force. And now? Chen Rui had played the hawk man in circles.    

Just now, the people of the Eagle Country praised their fighter aircraft in a cool manner, but what happened in the end? They couldn't even beat MiG 21!    

"When we go back, we'll give Chen Rui a first class merit!" General Zhang said. This time, Chen Rui had definitely made a great contribution.    

This would be beneficial to the upcoming negotiations. How much more do you want to sell your male cat for? We can also make a profit by relying on the J-7.    

"That's right, transfer him to the Air Force Division." Another general at the scene said.    

"Hmph, you still want to snatch this good seedling? He belongs to the Air Force Division."    

The generals of the Han Country were all extremely excited. In the sky, the intense battle was still going on. Although they could only see it on the radar screen, the scene was still very exciting.    

The two fighter jets flew towards each other. What happened next?    

Of course, they had turned around. Whoever turned faster would be able to catch up to the other party's butt.    

Just now, he had been bitten by MiG 21 for a long time. If he couldn't pull it back, then it would be too shameful! Now, when the two sides crossed each other, Brown immediately pulled the lever and pedaled the rudder. The wings were fully unfolded, ready to make a big circle and quickly turn to the back of the other side.    

At this time, Cross, who was behind, also temporarily gave up on operating the radar. Instead, he looked out the window. In an instant, he exclaimed again, "He's climbing!"    

That's right. After the two sides crossed each other, Chen Rui did not circle at the same level as Brown. Instead, he directly climbed up!    

Chen Rui turned on the acceleration and MiG 21 began to climb up lightly.    

Seeing this scene, Brown was also anxious. He suddenly turned on the acceleration, and then pulled the operating stick to climb up as well.    

But then, there was a vibration coming from his tail. When he felt the vibration of his body, he knew that he was in big trouble.    

The engine had failed again!
