机载综合光电系统的应用与发展

作战飞机微波隐身和电子战技术的不断进步,使得机载火控雷达的探测距离和抗干扰能力逐步下降,且雷达本身采用有源探测方式,工作时主动发射电磁波易被敌方发现、干扰和攻击。为弥补机载雷达的不足,体积小、重量轻、功耗小、角分辨率高、抗电磁干扰能力强、隐蔽性好,且以被动方式工作的机载综合光电系统不断发展起来。从现有光电探测系统的技术基础和任务需求出发,分析了机载红外搜索与跟踪系统(IRST)和光电分布式孔径系统(EODAS)等机载光电对抗系统的应用、功能、特点、装备现状及发展,并对新一代机载综合光电系统的要求及技术发展趋势进行了预测。

Application and development of integrated airborne electro-optic systems

With the continuous progresses of microwave stealth and electronic warfare technologies in combat aircrafts, the detection distance and anti-disturbance abilities of airborne radars are decreased gradually Meanwhile the active detection mode with emitting electromagnetic waves makes radars easy to be found, interfered and attacked. In order to make up for the weaknesses of airborne radars, integrated airborne electro-optical systems are growing quickly, which have advantages of passive mode, small vol weight, low power consumption, high angular um res strong anti-electromagnetic interference abil good concealment. From the technical basis and missionrequirements of existing electro-optical detection systems of view, the applications, functions, features, equipment status and development of airborne Infrared Search and Tracking （IRST） system, Electro-Optical Distributed Aperture System （EODAS） and other airborne electro- optical countermeasures systems are introduced. The requirements and technology trends of a new generation airborne integrated electro-optical system are predicted
