Can a fighter find itself locked by infrared?

2. The range of infrared search and locking is very small, and it can only be a seeker for close-range combat missiles. Missiles at medium and long distances cannot be used, let alone used by warplanes to search and lock on to targets.

3. When the enemy aircraft is locked through the radar, the general jet fighter is equipped with a tail guard, that is, a device that accepts the radar band of the enemy aircraft and sends out a buzzer warning.

How did a fighter pilot know that he was locked onto a missile? Experts say bluntly: information warfare!

I come, if the infrared missile is only passively locked with infrared, the pilot has no way to find it, unlike radar missiles, infrared bombs do not emit any rays but receive infrared radiation, so there will be no prompts. The SAM of the old United States said by LS is nothing, and the American MLWS acceptance is disc-type, and it is estimated that the SAM bomb part is the radar part is infrared.

Of course, the Missile Lauch warning system can detect the infrared rays produced by the emission of infrared bombs, and the emission (not a lock-on but a certain distance can be launched, and it is with tail smoke propellant) should be able to prompt.

In any case, although infrared bombs can lock onto the attack range is limited, based on the increase in radar stealth anti-radiation bombs, the growth of infrared bomb technology, which is not easy to detect, is still the second way for missile development in the future

That's why so many so-called stealth fighters were shot down by infrared, there is no way.

Upstairs said well, but people are asking about infrared missiles, a SAM red indicator on the old American dial seems to be for active radar guidance and semi-active radar guidance, infrared stinger, 9L, 9X also use this set?

Airborne warning radar.

It can detect that it is being scanned and locked by enemy agents, and at the same time sound an alarm.

Why is there a lock alarm when a fighter is locked by a missile, tell the fighter pilot.

In movies, fighter pilots are often seen saying, "I'm locked!" "How did they know they were locked onto the radar?

All of them rely on radio waves to convey information. When the radar of the fighter or air defense system locks on to the target, they will constantly emit radio waves of a certain pattern to the target, so as to continuously obtain the azimuth distance speed of the target, which can enable the fighter or air defense system to launch further attacks. So far, China can be said to be very successful in science and technology, and it is also very successful in military terms.

The fighter is equipped with a sophisticated self-defense system that can detect and judge whether the enemy is using radar, laser or infrared means to detect and track itself, or launch missiles at itself, through passive detection. The two most important devices in the self-defense system are the radar warning receiver and the missile approximation sensor, the prototype of which is the tail protector, which is used to receive the enemy's radar irradiation signal in a certain airspace behind the tail.

When the enemy follows and tracks the machine, the tail protector is captured by the enemy's radar, so it sends a light or audible warning message to the pilot to avoid maneuvering. The tail protector later evolved into an all-round radar warning receiver, which was connected to the received signal from the enemy's fire control radar in the 2 or 3 cm band for alarm. Modern advanced radar warning receivers have high detection accuracy of threat radiation sources and can be used for the guidance of anti-radiation missiles.

When a fighter or anti-aircraft missile locks on to the target, it is noticeably different from the search state. For example, if the search state does not continuously transmit radio waves to the target, it will need to be scanned once in a while to achieve the full-view search function. To know that you are locked by the other party's radar, you first need to be able to distinguish the relevant radio characteristics.

However, we can get access to the adversary's radar, and we can lock on to their signals.

Therefore, fighter jets are now equipped with radar warning systems and missile approach warning systems, and as long as the local fire control radar is locked and the missile is attacking, the pilot can be provided with the location of the local radar and the missile, so that the pilot can make correct evasive actions.

In movies, fighter pilots are often seen saying, "I'm locked!" "How did they know they were locked onto the radar?

Because the fighter device has a device that automatically tests the radar lock, if the radar locks on the fighter, the fighter will make a self-prompt and produce a state of self-protection.

To know that you are locked by radar, you first need to distinguish the relevant radio signature. The method of obtaining the opponent's radar lock signal mainly relies on the recording of the opponent's lock signal obtained through reconnaissance and storing it in the lock alarm of the opponent's fighter plane, so that once the relevant equipment is locked in the future, the alarm will be issued.

Modern fighter jets generally have anti-control radars and warning devices. Therefore, when you are locked by enemy radar, an alarm will appear.

To put it simply, the fighter plane's radar emits radar waves and hits the enemy and then turns back, and the fighter can receive the echoes and analyze the enemy's situation, but change the radar wave from receiving itself to receive the enemy.

It's systems engineering, reflected infrared, reflected ultrasonic, airborne radar, microelectronics, computer evaluation systems.

Missile lock alert via far-infrared detection radar.

There is a device called passive radar warning system on the aircraft, this system judges the radar-guided missile by detecting the radar wave, when the aircraft is scanned by the radar wave, he will sense the electromagnetic signal different from the surrounding environment and send out a scanning alarm, when the radar locks the aircraft, it will concentrate all the energy on the target, at this time the received electromagnetic wave signal will rise sharply, the radar warning system will send out a lock alarm, when the missile is launched, the frequency hopping of the opponent's radar will be fixed in a frequency band, Active-guided missiles will have their own radar signals, at which time the radar warning system will inform the enemy of the incoming missile, and indicate the direction of the missile according to the direction of the radar wave. The F-35 is equipped with an all-day photoelectric sensor and a full-day radar, as long as a missile is launched, the missile type, speed, and direction can be determined 20 kilometers away, and the most comprehensive early warning can be obtained. But this system is not always effective, for example, if the direction of multiple radars is similar, he can only detect one, and if he countermeasures according to his working principle, it can also make it invalid, for example, the APG-77 radar used by F-22 uses a low-frequency signal group to hide its own radar waves in the environmental electromagnetic waves, so that the opponent's passive radar warning fails, and the purpose of complete stealth attack is achieved.

In addition, if the opponent's missile is infrared-guided, the radar warning system cannot detect it.

The warning of the radar is not the same as the attack, the alert is scanned, the radar wave is periodically scanned, and the fire control radar during the attack will always illuminate the target, if it is continuously irradiated for a long time, it means that it is going to be attacked, and the alarm will be given.

Haha, when the missile is launched or the radar locks the aircraft, the radar wave will be emitted, and the aircraft has an instrument to detect the radar wave, and when the radar wave of the missile or radar shines on the aircraft, it will be detected by the instrument and alarmed.

In film and television works, we often see fighter pilots reporting to the command team that they have been locked by enemy missiles and need to evade and release jamming signals. This behavior often feels very sci-fi, in the air battlefield, the plane may not be visible to the naked eye, so how does the plane detect that it is locked?

There's a radar that'll find out when it's locked.

Radar warning is mainly used to detect the radar lock wave of enemy aircraft.

There's also an optical detection thing for missiles, I forgot what it's called

After World War II, when fighters were engaged in combat, they used a small shot control radar (similar to fire control radar, not exactly, it seemed to be called a ranging radar in the early days, and was first used on the F-86) to assist in targeting, this radar has a short scanning period and a narrow beam. The fighter is equipped with a radar warning device in the tail, and once it receives the radar signal of the enemy aircraft, it will give an alarm, and send out different frequency sounds according to the number of frequency points received from the opponent to prompt the pilot to take evasive actions. When the fighter is locked, the opponent's ranging radar wave will be received by a non-leaking alarm device, and the alarm will send out the highest level of alarm, and the pilot will know that he is locked.

When locked by the fire control radar of over-the-horizon missiles and surface-to-air missiles, the situation is similar to that of modern fighter jets, which is basically multi-functional, and one radar covers all scanning, fire control, and ranging.

The detection system of the general fighter is radar, and there are a few infrared detection as auxiliary equipment, on the contrary, the general third-generation fighter has a radar warning system, which will send out an alarm after being locked by the opponent's radar, and it is recommended that the pilot start to make a series of escape measures such as maneuvering to evade, release hot flares, jamming chaff, etc.

When a fighter is targeted by the enemy, it will be irradiated by the enemy's radar electromagnetic waves, which will generate an electric current on the metal part of the fighter jet, which will be sensed.

In fact, it is by detecting each other's radio waves.

To launch a missile, in most cases, it is necessary to target and lock through the radar, and the radar will continuously and strongly illuminate the target when it locks on the opponent's aircraft, and the radar wave signal at this time has the strongest and obvious characteristics, and the electronic system on the aircraft can detect it, so as to warn the pilot.

Detect radar waves or guided lasers emitted by the other party.

In movies, fighter pilots are often seen saying, "I'm locked!" "How did they know they were locked onto the radar?

Damn, my eyes have been opened, I want to know too!

Generally, there are many kinds of guidance methods after the target is fixed, but the air-to-air and surface-to-air missiles are all heat-tracking, infrared semi-active guidance, or airborne radar, air defense system active guidance, when the target is fixed, it will emit an electromagnetic pulse band to irradiate the target, and the instrument of the target itself will detect the signal sent by the semi-active missile or the electromagnetic pulse band emitted by the active guidance**, so as to make a response, and the difference between the active-guided missile and the semi-active guidance is that the active-guided missile is not the missile itself, and the target is before launch Radar or detection equipment has already set the target (the same is to send an electromagnetic pulse signal to the target, the target instrument will also detect that it has been irradiated) to launch an active-guided missile, active-guided missile, it is more difficult to get out, the anti-jamming capability is strong, the power of the semi-active guided missile is relatively large, but the maneuvering energy and anti-jamming ability are poor, but the structure is simple, and the cost is low.

The fighter is equipped with a radar warning device, which will emit an alarm sound to alert the pilot to evade after the aircraft is locked by the enemy's fire control radar (continuous irradiation of electromagnetic waves).The principle is that when the aircraft is continuously irradiated by radar waves (locked), the sensors buried inside the skin of the aircraft will alert the aircraft, and the fighter pilot will know.

The dream melody is clearly pasted.

If some devices are installed, it will, because the infrared homing missile tracks the target with the infrared rays emitted by the fighter engine, and does not emit any signal itself. If some device is installed on the fighter (I don't remember the exact name), the missile can be detected by ultraviolet light in the flame in the tail of the missile.

Of course, there will be an alarm, the passive infrared has a locking guidance head, and it will send a certain search signal, so the aircraft will call the police, but now in the war, if the other side has a strong electronic warfare force, it may be that the aircraft will keep ringing from the start of the alarm, like the MiG-29 of the Federal Republic of Yugoslavia will be like this when it is dispatched to fight NATO. The pilot had no choice but to turn it off.

Fighter jets will not civilian aircraft.
