385 towed active radar bait

There was a constant alarm sound in Chen Fei's cockpit.

There were several places on the radar alarm at the same time, which were terrifying warning signs flashing.

At this time, the voice of the early warning aircraft also came, informing the crisis Chen Fei was facing at this moment.

At this time, it would be fake to say that Chen Fei was not nervous at all, and his heart was also raised to his throat.

But he was nervous but not panicked, and felt danger but not confused.

He turned his head and looked at the tracks of several missiles behind him that were chasing him. Soon, he withdrew his gaze, pressed the pole, and dived.

The height advantage he had previously occupied was completely transformed into speed at this moment.

Whoosh!

Fighters are like a stream of light, passing through the air like electricity.

Chen Fei dived almost vertically.

Such dives can give him enough speed, and nearly vertical dives will quickly disintegrate the missile's energy. In addition, vertical dives will also make it more difficult for the missile's searcher to search the target, because the ground clutter is very disturbing in the vertical direction.

But there are also bad things about vertical dives, that is, its overload is too large, and many pilots will soon be unable to bear it, which will eventually lead to plane destruction and death.

Fortunately, Chen Fei has a very high ability to carry lots and he can withstand it.

Although Chen Fei's height when he started diving was about 8,000 meters, it was actually only 3,000 meters away from the ground. Because the mountains below were very high and the altitude was 5,000 meters, to be honest, Chen Fei's diving distance was not much, only more than 2,000 meters. It was impossible for him to dive to a place thirty or forty meters above the ground before pulling it up. That would be too dangerous.

But he could not pull up fighter jets at too high places, because his purpose was to use the ground to get rid of missiles, so his plan was to pull up when the fighter jets were 500 meters away from the ground. In this way, when he changed it, the fighter jets might be about 2,100 meters away from the ground. This distance is almost impossible for missiles to avoid, and they will definitely hit the ground.

When Chen Fei dived to a height of 450 meters above the ground, he pulled up the operating lever. The huge overload made the fighter make a sour sound, and it seemed that it was about to fall apart. Fortunately, the J-20 was still very solid and there was no accident in the fighter.

This nearly ninety-degree turning point - rushing down vertically and then pulling up horizontally to change it - this huge maneuvering action made the two missiles chasing Chen Fei unable to complete the maneuver, and they all fell to the ground and exploded.

But there was another one, he was the last one to be launched, so it was far away from Chen Fei. Therefore, when he was still a long distance from the ground, the pilot who fired him urgently sent a radio to change his flight route. So he forced a stance in the air and continued to shoot towards Chen Fei.

Chen Fei took a look at the electronic tactical threat display. On it, the radar radiation signal of the missile was getting stronger and stronger. Therefore, there is no doubt that this is an active radar-guided missile. This should be a medium- and long-range air-to-air missile. Such missiles generally have the opportunity to ignite twice. However, this missile is still in the first stage, which is the stage of relying on inertial flight. In other words, his engine has not ignited twice.

This is the big threat!

Chen Fei's eyes narrowed slightly.

He glanced at the terrain outside for a while, fled quickly in the fighter plane, and then glanced at the electronic tactical threat monitor, carefully observing the missile.

Soon, the missile was fired again!

Because of the electronic tactic threat display, the increase rate of radar radiation signal of this missile suddenly increased and accelerated. Before, although the radiation signal of this missile became stronger and stronger, the increase was getting smaller and smaller, which means that its speed was getting slower and slower. But now, the situation is the opposite, the increase of signal is getting stronger and stronger.

Chen Fei had been prepared before and immediately used the electronic jamming equipment provided by the fighter to electronically interfere with the guided radar of the missile!

At this time, his hands were dazzled, and a tiger was operated by a dazzling tiger. After an instant, a group of foil strips were put out, a group of bait bullets were thrown out, and then a group of foil strips and a group of bait bullets were added.

For this medium and long-range advanced air-to-air missile that can ignite twice, try not to be lucky enough to use maneuvering actions to get rid of him. If you want to avoid him, the only possibility is to use a bait bomb to detonate him as soon as possible, or use electronic interference!

However, after Chen Fei operated the Tiger, the missile was not detonated and was not successfully interfered by the electronic warfare system!

He was just a moment of confusion and quickly woke up. He immediately continued to chase Chen Fei, and the distance was getting closer and faster.

Obviously, this is not an ordinary medium and long-range air-to-air missile, it should be the most advanced type of the enemy.

At this time, the alarm sound in the cockpit sounded again, and it became more and more sharp.

In addition, the suffocating and terrifying feeling in Chen Fei's heart also filled his whole body.

The final killer must be used!

Otherwise, you can only eject the skydiving!

However, skydiving at such a high place is equivalent to skydiving on the Qinghai-Tibet Plateau in our country. Even if you jump down and are not killed by falling to death, you will probably be frozen to death. You cannot jump here unless you have to.

Chen Fei decided to use towed active radar decoy (TRAD).

The basic principle of towing bait is to tow the bait using the towing device on the aircraft, so that the bait not only leaves the aircraft, but also has the same motion characteristics as the aircraft. It will not be quickly identified by the active radar seeker of modern missiles like foil strips.

Releasing this bait by the carrier aircraft is equivalent to forming a virtual dual-machine formation. Through maneuvering, the "virtual wingman" of the drag bait is closer to the incoming missile, and using the seeker to catch the big and let the small, to grasp the bait with stronger signal characteristics, and to achieve "losing the car to protect the coach".

The towing device is actually very similar to an old friend in the field of aviation weapon testing and training - aviation tow targets, and is not complicated;

If you just replace the target with an angle reflector that increases the signal strength of the bait itself, it is indeed not difficult to technically, but it is difficult to achieve "real appearance" from multiple angles and is easily recognized by modern radar seekers. Especially when facing incoming missiles, a "wingman" that will not interfere is obviously not deceptive and will not play much role in addition to dragging the maneuverability of the carrier.

So now generally speaking, drag bait refers to TRAD with its own jammer. The principle is to transmit the interference signal to the desired transmission through the towing line between the carrier and the bait (the power required for the interference signal is also transmitted by the carrier). The transmitter on the bait simulates a radar signal characteristic similar and stronger than the carrier and has interference conditions. In this way, TRAD forms a pair of "virtual wingmen" with the carrier that is also releasing interference.

In various live-fire target tests at home and abroad, it was also found that although the relative consistency of the movement posture between the target and the bait makes it difficult to identify even seekers that adopt the pulse Doppler principle at a long distance; however, as the distance between the missile and the target is close, the angle between the connection between the missile and the target and the connection between the missile and the bait becomes larger and larger, and some seekers with higher speed resolution and larger detection ranges (to ensure that the missile/bait are all within the "field of view") have significantly increased.

In live ammunition, some other surface-to-air missile systems that still retain command guidance technology use another set of methods: when the performance of the radar system is not as good as that of advanced models, the missile can track the bait interference source mode through command control, and combine the pre-arrangement method of changing the target parameters to attack the target aircraft mounted on TRAD.

The logic is that since the missile seeker cannot identify the target and bait, the bait cannot be "torked" in front of the aircraft anyway, then based on the length of the existing TRAD towing rope and the heading of the target/bait relative to the position, adding a "advance" while using the pre-position method can theoretically increase the probability of damage.

Chen Fei is now using such an advanced towed active radar bait.

He operated the tiger, and the missile was finally detonated with a loud bang. The huge impact force made Chen Fei's fighter tremble and almost slipped. Fortunately, Chen Fei pressed the pole and urged the rudder in time, and then corrected the aircraft's posture.

Although he got rid of the pursuers behind him, this did not mean that he was safe, because soon, the early warning aircraft sent a warning: "Eagle, at three o'clock in front of you, seventy kilometers behind the Longermei Mountains, a two-plane formation is taking off. It is speculated that they will ambush you there, be careful."

Although Chen Fei's airborne radar was on, he could not see the two aircraft formation due to the obstruction of the mountains.

Fortunately, he still has the support of early warning aircraft.

Moreover, the closer they get to the base, the stronger their early warning capabilities will be, and the safer they will be.

But if you want to return to the base safely, you still can't expect it for the time being, unless he can win the previous battle.

Chen Fei glanced at the oil gauge.

Oh shit!

Less than half of the burning was left, and it was impossible to fly to the Sanjiang base.

After thinking about it, he used a radio: "Tiangong No. 1, I don't have much fuel left. You have to think of a solution for me, either find me a nearby airport to prepare for landing, or you send me a tanker!"

Chen Fei felt at ease by the early warning aircraft's answer. The early warning aircraft said: "Eagle, you don't have to worry about fuel. The tanker is already on the way. It is expected to meet you near the next navigation point, and it is finished!"

Next navigation point?

Chen Fei recalled the return route map.

Fortunately, the next navigation point is not too far away. The remaining fuel in his fighter is enough for him to fly there. Even if he keeps flying supersonic in the middle and drives a few more times of force, it is enough.

Chen Fei quickly thought about the next flight plan.

It seems that I can only deviate from the return route a little bit for the time being. There is an ambush at three o'clock in the front, so he would better avoid it. He only has one air-to-air missile now, so he can't compete with the other party for a cannon. He thought, but would he be so stupid?

He pushed the rod to the left and took off.

While leaving the original route, he used a radio channel: "Tiangong No. 1, carefully observe the movements of the two aircraft formations and inform them at any time! It's over!"

"Received! We will inform you immediately if there is any situation!" said the early warning aircraft.

The main reason for letting the other party inform him at any time is that Chen Fei had a vague feeling that the enemy would not let him go back so easily, and it was impossible for him to just send a two-plane formation to ambush, because once he passed the previous section safely, it would be impossible for the enemy to shoot him down again, because after the previous section, the frontier positions of the US coalition were in the frontier positions of the US coalition, and the ground guide troops of the US coalition were everywhere on the ground. Although the equipment of those troops was a bit out of date, so many ground missiles were aimed at the target together, and not many pilots could escape.

So Chen Fei had a vague feeling that the previous section should be the last battlefield, and the enemy must have laid ambushes here. Even if the enemy could not react in time, there should not be only one two-machine formation.

Sure enough, after flying for a while, Chen Fei heard the sound of the early warning aircraft: "Eagle, there is an abnormal movement in the formation of the two aircraft at three o'clock. They flew towards you!"

Um?

Chen Fei frowned.

They seemed to know they were flying to this side!

He hurriedly asked the early warning plane: "Tiangong No. 1, do they also have early warning planes nearby?"

"No!"

No?

Chen Fei's pupils shrank.

The enemy's most advanced early warning aircraft has been killed by him, so there is no possibility that our army's early warning aircraft cannot detect it. Therefore, the two-machine formation knows his movements and cannot be credited to the early warning aircraft. Therefore, there is no doubt that they have other accomplices, who use advanced photoelectric detection systems to detect him. Therefore, there is nothing on his electronic tactical threat display, but the enemy knows his whereabouts clearly.

Is the photoelectric detection system?

Chen Fei smiled faintly.

After thinking about it, he said to the early warning aircraft: "Tiangong No. 1, their photoelectric detection system is very advanced!"

"We have recorded it and hand it over to the intelligence department immediately after the mission is completed, so that they can seize the time to collect information on this aspect!"

Chen Fei smiled and said nothing. He turned his head and looked down. There was a thick cloud floating about seven or eight hundred meters above the mountain. As long as he hid inside, the enemy's photoelectric detection system would definitely be useless.

His J-20 fighter is originally full-spectrum stealth and has strong stealth capabilities for infrared detection. However, there is no doubt that the photoelectric detection system equipped by the enemy must be more advanced, but no matter how advanced it is, it is difficult to penetrate such a thick cloud, just like no matter how advanced the spy satellite is, it is afraid of encountering cloudy days.

He pressed the height of the rod and quickly got into the clouds.

Soon, the sound of an early warning aircraft sounded on the radio: "Eagle, I found another two aircraft formation, at your eleven o'clock position, fifty kilometers away."

Chen Fei looked down at the multi-function display, and the data link of the early warning machine displayed all the data they detected one by one.

At this time, the two formations had already drilled out of the rolling mountains and were not hiding them, but they did not turn on the radar, but approached quietly.

The sea of ​​clouds that Chen Fei was hiding was very big, but no matter how big he was, he still had a limit. There was always a time to fly, so the two fighter jets quietly flew towards the end of the sea of ​​clouds, wanting to ambush there.

Chen Fei guessed their attempts clearly based on the data transmitted from the early warning aircraft.
