With the continuous improvement of people's requirements for air combat capabilities, J-11FightersofRadarThe system has also undergone several stages of development and upgrading. Today, the J-11FightersIt is carriedAirborne radarIt has become one of the strongest in the country and is known abroad"Flankers are the strongest", thanks to its continuous technological progress and evolutionary process.
1. Initially equipped with NO01E radar
Since J-11FightersSince the first test flight, itsAirborne radarIt has always been used by the Russian NO01ERadar。no01eRadarFor probesFightersWith a forward range of 100 km, large and small targets can track up to 10 targets at the same time, giving priority to the most threatening targets. However, due to NO01ERadarThe level of technology is low, and there are many problems, such as:RadarIt does not have a full waveform, only high and medium pulse repetition rate, no low pulse repetition rate, and the anti-interference ability is poor, the side lobes are large, and the processing systemComputing speedlow, poor reliability, etc. Due to NO01ERadarUnable to meet the requirements of air warfare in the 21st century, ChinaAir ForceIt was decided to replace it with domesticRadar
2. Localization improvement
ChinaAir ForceAware of the J-11FightersIt needs to be replaced with domestic productionRadarin order to achieve greater combat capability. Beginning in 2000, China introduced the R-77 initiative from RussiaRadarGuided air-to-air missile, which is a domestic refitting of the J-11RadarPaved the way. Until then, for use during the transition period, we will be no01eRadarUpgrades were carried out, this time carried out by the technical cooperation of the Belarusian Plant 588. Improvements include upgradesRadarThe signal of the data processing system, replaced with a new computer to improveRadarperformance, and with the new mode of operation and。Despite the limited effect of the improvements, the upgrade was made to the J-11FightersWith the R-77 activeRadarThe groundwork was laid for guided air-to-air missiles.
3. Localization of J-11B
With ChinaAir ForceRealize the national production of J-11J-11BFightersEquipped with domestic pulsesDopplerFire controlRadar, thisRadarA flat panel slit array antenna is used, and it has full waveform capability and a programmable signal processing system. This makesRadarhas a detection range of more than 150 kilometers and is capable of simultaneously tracking 12 targets, 4 of which are the most threatening. TheRadarWith the domestic PL-12 activeRadarGuided air-to-air missiles are used in combination to make them one of the most powerful over-the-horizon air combat combinations in the region.
4. The J-11BG has an on-board active phased array radar
Since 2010, globalAirborne radarEntered activelyPhased array radarEra. J-11BgFightersofRadarThe system was also upgraded and replaced with a domestic airborne activePhased array radar。Thanks to the J-11FightersThe internal space is larger, the energy and cooling capacity are stronger, and it is equipped with a domestic aircraft with an active forcePhased array radarFavorable conditions were provided. NewRadarThe antenna aperture is close to 1 meter, and more than 2,000 T R modules can be arranged, so as to obtain huge power. Its detection range can reach or even exceed 200 kilometers, and with the domestic PL-15 medium and long-range air-to-air missile, it forms one of the strongest air combat combinations in the region and even the world. In addition, the airborne activePhased array radarIt also has a variety of functions such as:DopplerSharpened, synthetic pore sizeSurveying and mappingand ground target designation, etc., in precision to the groundStrong support is provided in terms of delivery.
Through the elaboration of this article, we learned about the J-11FightersRadardevelopment and evolutionary process. From the original NO01ERadarto the improvement of localization, and then to today's airborne activePhased array radar, J-11FightersofRadarThe system has gone through multiple stages of development and has gradually realized localization and upgrading. Airborne active of a new generationPhased array radarMake the J-11FightersIt has reached new heights in terms of air combat capabilities, becoming one of the strongest in the country, and has also been praised abroad.
As an editor, I feel it all too wellRadarTechnology forFightersThe importance of performance. RadarAsFightersof"Eyes", which plays a vital role in modern air combat. With the continuous advancement and innovation of technology, I believe in the future J-11FightersofRadarThe system will continue to develop and improve and make greater contributions to China's national defense cause.
