Super Weapon Swap System

What's the weakness of the male cat fighter?

To be exact, this is not the weakness of the male cat, but the common weakness of all pulse doppler radars.

The working principle of pulse Doppler radar is not complex. When the radar transmits a fixed frequency pulse wave for air scanning, if the Doppler radar encounters a moving target, the frequency difference between the echo frequency and the transmitted wave frequency is called Doppler frequency.

If it is a fixed target on the ground, this is a certain value, which can be removed in the radar processing system.

What are the benefits?

Before the emergence of pulse Doppler radar, ordinary monopulse radar could not detect targets flying at low altitude, because there were so many undulating ground and various buildings at low altitude, which were reflecting radar waves. On the radar screen, it was definitely a snowflake.

Only by filtering out these ground signals can we accurately find the target. In this way, we can find out those ultra-low altitude aircraft trying to use terrain cover.

This principle is very tongue twisty. If you have taken a train, when two trains meet, or on the platform, watch the train enter the station and hear the whistle of the train.

Originally, in the distance, the train came all the way, but when it approached, the sound would change and become higher. This phenomenon is Doppler phenomenon. It is because the frequency of sound changes when the train passes.

After talking for a long time, pulse Doppler radar is very powerful, but it is also flawed. Sometimes it misses the target. For example, he could not find or attack an enemy plane flying in the same direction and at the same speed as himself. At the same time, he could not attack the target perpendicular to his plane. At this time, the target was filtered out like the ground stationary target.

At this time, it has to be converted to PSTT mode. Single pulse, without Doppler function, will not be filtered out.

But it takes time.

Just as cross in the back cabin switched, Chen Rui had flown out of the clouds.

Just now, he was inside the cloud. When the humble radar warning receiver of MIG 21 found that there was radar wave scanning, he flew out. At the same time, he also flew to the direction perpendicular to the other party's heading.

Therefore, the other party can't lock Chen Rui.

This is a common tactic in air combat, but it absolutely needs the superb skills of the pilot, because it must fly vertically properly, which is completely the instinctive reaction of the pilot.

However, this also means that MIG 21 is gradually away from each other. How can he get close?

Of course, it's half a turn and then fly backwards.

Just like the ancient sailing age, can sailing only sail with the wind? Of course not. For experienced sailors, they can grab the popular ship. At this time, the ship is definitely not going against the wind, but taking a zigzag back and forth route, so they can go against the wind.

Now, after half a turn, the course remains unchanged and is still perpendicular to the other party's route. However, the distance is close. Flying back and forth repeatedly in this way forms an S shape, also known as snake turn. This technology is of great value in the old hands.

In later generations, some backward aircraft broke through the long-range protective net that the eagle people were proud of and directly killed them by relying on this maneuver.

Now Chen Rui is like this. He makes a snake turn and has successfully killed the other party in front of him.

If your sword is not long enough, take a step forward! Even in this era, the air bayonet still works. When your plane is not advanced enough, use tactics to make up for it!

In the tower, the eagle people have gradually become silent from their shock. They look at the state on the screen and see Chen Rui kill the male cat with the spirit of not afraid of death. Their mood is complex.

So far, the male cat fighters have been suppressed. They don't even have a chance to turn the radar into PSTT and lock it again. They have come to the front!

Even if the male cat can lock the opponent in the end, the MIG 21 is still proud of its defeat. So far, the male cat has not gained the upper hand, which is a failure.

Han is a terrible country. All their pilots are not afraid of death! At first, in the beautiful sky, they were like this. The newborn Han air force frightened the ace Eagle Navy and air force.

Such an air force is admirable.

Flattering others is useless. Only by proving yourself with strong strength can you win the respect of others, just like now.

As for general Zhang, he was already too happy to close his mouth.

As long as he is not locked and killed immediately, Chen Rui will have a long face for the air force, and now? Chen Rui played the eagle people around.

Just now, the eagle people praised their fighters so smartly. What happened? Not even MIG 21!

"After going back, write down the first-class merit to Chen Rui!" said General Zhang. This time, Chen Rui has definitely made great contributions.

This is also very beneficial to the next negotiation. How much more does your male cat want to sell for this ability? We can also fight rivers and mountains by J-7.

"Yes, transfer him to the 1st Air Division," said another general at the scene.

"Hum, you still want to rob this good seedling. He's from our 3rd air division."

The air force generals of the Han Dynasty were excited at this time, and the fierce battle continued in the sky. Although they could only be seen on the radar screen, the scene was also very exciting.

Two fighters, almost head-on, flew by. What's next?

Of course, it's a turn. Whoever turns fast can catch up with each other's ass.

Just now, I was bitten by MIG 21 for a long time. If I can't pull it back, I'll lose face! Now, when the two sides crossed, brown immediately pulled the lever to pedal the rudder and spread the wings, ready to make a big spin and quickly turn behind each other.

At this time, cross in the back also temporarily gave up operating the radar and looked out of the window. In an instant, he screamed again: "he's climbing!"

Yes, after the two sides crossed, Chen Rui didn't hover horizontally like brown, but climbed up directly!

Chen Rui opens the afterburner and MIG 21 starts to climb up lightly.

Seeing this scene, Brown was also worried. He suddenly opened the afterburner, then pulled the operating lever and climbed in the circling.

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

The engine is off again!
