PS mode, is the fighter radar basically has a function, even if it is the 204 radar on the J-8 fighter, if classified, the search function on the radar is this, referred to as pulse search.

This mode is only a state that works in the pulse mode, its task is to search, except for the direction of the target, there are no other parameters, and when the search is out, it will be converted to PSTT, and you can launch an attack.

Although it is the same as the PDS mode, it is a search, but the lack of Doppler performance also brings a significant decrease in overall performance.

For example, the detection range has dropped significantly, probably at a discount compared to the PDS, and at this time the Tu-95, B-52 and other big guys are almost close to 160 kilometers before they can be detected by AWG-9.

Therefore, under normal circumstances, the radar officer will not choose this mode, there is no advantage, a lot of chicken ribs.

And its only, the advantage is to avoid some blind spots in the PDS mode, such as the same direction and speed target, traversal track target, etc., because there is no Doppler filtering, so, those targets will be searched out, can be simply summarized, PS mode is not very useful, generally used to make up for PDS blindness.

When the other party uses the shortcomings of Doppler radar to hide their whereabouts, this kind of pulse search is the most suitable.

However, this time, Qin Feng didn't give them a chance, after all, the mode change of the radar also takes time.

Just when he found the target and saw that the other party was turning in a serpentine shape, Edwards immediately decided to use the pulse search mode to find the target, but now, Qin Feng's fighter plane had taken advantage of this opportunity to easily kill them!

Edwards was stunned, and the opponent's strong fighting momentum shocked him.

If he'd read a book called Bright Sword, he would have known that there was a sentence in it, if your sword wasn't long enough, take a step forward!

A brave swordsman, no matter how strong the enemy is, dare to show his sword! The MiG-21 is so weak in front of the Tomcat fighter, but the brave Chinese pilots still dare to show their swords!

The radar is already in the best working condition, Qin Feng's hand flicks the knob and switch on the radar to lock on the target!

The piercing sound of the radar warning receiver from the earset made Edwards believe that the other party had successfully locked on to himself with radar, and he was still flying head-on!

This is simply a shame for the Tomcat fighter!

However, according to the regulations, it does not mean that as long as it is locked, it can be judged to fail immediately, and it must be continuously locked.

Yes, it takes time to lock on to the target and launch missiles, medium-range radar missiles must be irradiated all the time, and close-range missiles also need enough time for the fire control system to calculate the data, so at least it must be locked and last for more than three seconds to count!

Edwards' hand pushed the throttle stick and turned on the afterburner again, and he was going to take advantage of a dashing sideways turn to get rid of the other.

The engine in the tail changed violently again, from almost idling to full power just now, Edwards turned on the afterburner switch, and at the same time there was a huge push back feeling behind him, he heard the sound of snorting, and with the sound, the whole body trembled.

Not good, engine surge!

This malfunction, almost every pilot of the Tomcat fighter, as a test pilot of Grumman, of course, is even clearer.

The TF30 engine was originally intended for bombers, so the engineers at the engine plant complained that the pilots drastically changed the speed of the engine, but, in the heat of air battles, who doesn't want to have a strong engine?

The pilot is quite dissatisfied with the engine, and in the fierce confrontation, he has to pay attention to the engine all the time, and if he is not careful, he will drop the chain!

When the tail turns on the afterburner and injects more fuel, the compressor in front of it can't press in enough air, and in this way, in the rapid change of airflow, the compressor can't bear it, just like an old man with an asthma attack, he will stop after a few snorts.

If it were an ordinary pilot, the engine would definitely have to stop, but now Edwards is an excellent test pilot, he immediately turned off the afterburner, released the throttle lever, and then pushed the operating lever, the fighter dive downward, and all of a sudden there was enough air to enter, and the engine gasped a few times and came back to life.

However, the sound of the radar alarm receiver in the headset has not disappeared for more than ten seconds! It was not until the MiG-21 flew in front of them that it was over.

Although at this time they can bypass, approach each other from behind, and turn on the radar to lock on the target, but, do they have the cheekiness? If it was in battle, they would have already been shot down.

On the ground, the Americans were also stunned.

Qin Feng's series of battles showed his superb flying skills and ability to capture fighters, using passenger plane cover, serpentine maneuvers, etc., which were almost impossible to do, all of which were done by him.

If it was a war, Qin Feng might have been shot down as soon as he took off, but now, in this confrontation, Qin Feng did win, and he used the backward radar of the MiG-21MF to successfully lock on the Tomcat fighter for ten seconds!

General Lin smiled, and wrinkles piled up on his face: "This kid, I knew he would definitely do it!" Such a good seedling, I really want to transfer him to the fighter unit, Tu Lao, let's discuss? ”

Tu Lao was still in a huge shock, and he didn't react that General Lin was poaching people: "Qin Feng, how did he do it?" It's incredible. ”

Compared with the excited Chinese, the people of Grumman Company present had shock, incredulity, and a hint of respect on their faces.

China is a miracle country, back then, in the sky over North Korea, they used to beat the US Air Force very badly, established the MiG corridor, and now, they fly a small MiG-21, they can actually defeat their own Tomcat fighters, if this matter spreads, Grumman will be laughed out of the big teeth!

Their mood was complicated, they all fell silent after hearing that Qin Feng's fighter radar had locked on the Tomcat, this confrontation made them very embarrassed.

I hope that in the future they will not become opponents with China, as opponents, they are terrible! They are good at miracles!

The mood of those present was heavy.

At the end of the confrontation, there was little fuel left for both aircraft, so they began to return one after another, and because of the defeat, the Tomcat fighters deliberately lagged behind, allowing the MiG-21 to fly back to the base first, and at the end of the runway, everyone was waiting eagerly.
