Recently, according to "Jane’s Defense Weekly" report, according to the latest satellite photos, the JY-27A anti-stealth radar has appeared in Pakistan’s Alan Air Force Base, which indicates that the Pakistan Air Force has begun to test this radar and will soon This radar is officially equipped. The Alan Air Force Base is the main place for Pakistan to test new weapons and equipment, including Xiaolong fighters, LY80 air defense missiles, and Rainbow 3 UAVs that have all been tested here and soon equipped the Pakistani army.
JY27A is a meter-wave three-coordinate long-range air surveillance radar. The radar antenna adopts advanced two-dimensional digital phased array technology. It uses both the very high frequency band and the ultra-high-power aperture product technology to deal with stealth aircraft, and the meter-wave radar itself It has a relatively good restraint effect on the shape of stealth aircraft and the wave-absorbing coating, so the JY27A radar has a strong ability to detect stealth fighters. In May 2020, Venezuela used the JY27A radar to successfully capture the F22 fighter. If Pakistan is equipped with JY27A radar, then it is the Indian Air Force's turn to have a headache.
The Indian Air Force has confirmed that it will be equipped with the Rafale at the end of July. The French company Dassault once claimed that the Rafale is a quasi-stealth fighter. Due to the adoption of stealth technologies such as S-shaped inlet and wave-absorbing materials, the Rafale’s radar reflection area Only 0.1 square meters, only one percent of the Su-27 fighter, can greatly reduce the range of radar detection. The F16 and Xiaolong fighters equipped by the Pakistan Air Force are only equipped with flat-panel slot antenna radars, and the detection range of the Rafale fighters is limited. In order to effectively intercept the Rafale fighters, the JY27A radar is required for early warning.
Xiaolong fighter currently uses the KLJ-7 flat-panel gap radar, which has a detection range of 130 kilometers for small fighters. Considering that the radar reflection area of Rafale fighters is much smaller than that of light fighters, the detection range of Xiaolong fighters against Rafale fighters may be It will be compressed to 60-80 kilometers, and the locking distance may be only 50 kilometers; and the SD10 air-to-air missile used by the Xiaolong fighter has a range of more than 80 kilometers, and it cannot exert the maximum power of the air-to-air missile when facing the Rafale fighter. For the same reason, the F16 was unable to exert the maximum power of the AIM120 air-to-air missile when facing the Rafale fighter.
In this case, the JY27A radar is needed. The detection range of the JY27A radar exceeds 350 kilometers, and the Rafale fighter can be detected early. Although the JY27A radar uses meter waves, the detection accuracy is not high, but it only needs It is enough to pass the approximate position of the Rafale fighter to the Pakistan Air Force fighter. The Pakistan Air Force’s opportunity to use the airborne radar to detect this airspace in a narrow beam way can increase the detection and locking distance by "concentrating energy". Lock the Rafale from a long distance.
On the other hand, India is developing its own AMCA stealth fighter, the JY27A radar will become Pakistan’s weapon against AMCA fighters. It is necessary to know that the JY27A radar can detect even F22 fighters, and the detection range of AMCA fighters will be more impressive, which will make the Indian Air Force lose its stealth advantage.
