雷达新一代战斗机雷达正在研制中,它们以F-22的有源电子扫描阵(AESA)雷达为代表。这种雷达由1000多个发射/接收(T/R)模块组成,每个模块能产生约10瓦的平均功率,总峰值功率可达兆瓦级。其波束能迅速改变方向或波形,故在以交替模式工作时,可迅速由一种模式转换成另一种模式,两种模式对航空电子系统来说似乎同时发生,好像有两个不同的雷达在工作。可靠性高是AESA雷达的重大优点,它不会突然发生故障,即使有几个T/R模块失效,性能也不会显著降低。据说这种雷达的无维修寿命可达20000小时,与飞机寿命相同。
Radar next-generation fighter radar is under development, represented by the F-22 active electronically scanned array (AESA) radar. The radar consists of more than 1000 transmit / receive (T / R) modules, each producing about 10 watts of average power and up to a total megawatt of total peak power. Its beam can quickly change direction or waveform, so when working in alternate mode, it can quickly switch from one mode to another. Both modes appear to occur simultaneously to the avionics system, as if two different radars working. High reliability is a major benefit of the AESA radar, which does not crash suddenly and does not significantly degrade performance even if several T / R modules fail. It is said that this radar without maintenance life of up to 20,000 hours, the same life with the aircraft.
