With the J-11FightersAs we approach the 25th anniversary of our maiden flight, we can't help but recall how the aircraft has evolved over the past few decades. And perhaps the most striking of these is thisAirborne radarof upgrading and development. From the beginning of RussiaNO01E radar, to later domestic pulsesDopplerFire control radar, and then to today's domestic airborne activePhased array radar, J-11FightersofRadarThe system has made significant progress in its continuous evolution. This article will focus on the J-11FightersRadarThe development process is in-depth**, and the reasons why it is known as the "strongest flanker" in the world.
, J-11FightersInitially equipped with RussiaNO01E radar。According to the information provided by the Russian side, theRadarIt shows good performance in both the detection range and the number of target tracking. However, due to the lower level of technology, this oneRadarAt that time, the performance was not highly praised in China. ExceptRadarIn addition to the low level of technology and the lack of anti-jamming capabilities, there is also the absence of the ability to use the R-77 activelyRadarthe ability to guide air-to-air missiles, etc. Therefore, in order to increase the combat capabilities of the J-11, China decided to proceed after thisRadarUpgrade.
In order to meet the needs of the J-11 with R-77 missiles, China toNO01E radarImprovements have been made. Through technical cooperation with the Belarusian plant 588, improvements were mainly focused on the upgrading of signal data processing systems and computers. This improvement is limited, but it still makesRadarPerformance has been improved. However, due to the fact that in the same period in China, flat slit antennas with full waveform capabilities have appearedRadar, thereforeNO01E radarIt has not been further introduced and promoted.
With the J-11FightersThe national industrialization plan is carried out, pulseDopplerFire control radarThe localization of the country has also become an inevitable trend. InJ-11B fighteron, a new type of domestic pulseDopplerFire control radarto be equipped. This one uses a flat slit array antenna and full waveform capabilityRadar, showing a high level in terms of detection range, target tracking ability and firepower strike capability. With the domestic PL-12 activeRadarGuided air-to-air missiles, makeJ-11B fighterBecome one of the most powerful over-the-horizon air combat combinations in the region.
With the globeAirborne radarThe further development of technology, activePhased array radarIt has become a new trend. ForJ-11BGFightersIn terms of replacing the domestic airborne activePhased array radarIt has become an inevitable choice. Due to the abundant space of the J-11 fuselage and its strong energy and cooling capabilities, it is active to replace the aircraftPhased array radarGood conditions are provided. ThisRadarThe antenna aperture is close to 1 meter, and it has more than 2000 T R modules for more powerful power output. The detection range can reach or even exceed 200 kilometers, with the domestic PL-15 medium and long-range air-to-air missile, so that theJ-11BGFightersIt has a strong advantage in air battles in the region and even in the world. In addition, the airborne activePhased array radarIt also has the characteristics of multi-beam and electronic scanning, etc., endowingRadarExcellent multi-purpose performance such as:DopplerSharpened, synthetic pore sizeSurveying and mappingand ground moving target designation, which provides strong support for accurate ground strikes.
Through the J-11FightersRadarLooking back and analyzing the development process, we can clearly see that over the past few decades, the J-11FightersofRadarThe system has undergone continuous upgrades and improvements, from the initial technical level to a lower levelNO01E radar, developed to the domestic with full waveform and active phased array capabilitiesAirborne radar, its combat capabilities have been significantly improved. From a global perspective,J-11BGFightersThe on-board activePhased array radarThe Combo is undoubtedly one of the most powerful air combat combinations available today, and will continue to play an important role in the battlefield environment beyond 2030 with its superior detection range, target tracking capabilities, and multi-purpose capabilities. AsChina AirlinesThe pride of industry, the J-11FightersofRadarThe development process is not only a reflection of technological progress, but also a symbol of China's important breakthroughs in the field of avionics. In the future, we can expect the J-11 seriesFightersofRadarThe system continues to innovate and forge ahead to better serve the needs of military development.
