雷达抗电子干扰措施(ECCM)用以削弱或对抗各种电子干扰措施(ECM)对雷达的干扰,通常雷达ECCM要避开干扰频率,削弱进入接收机的干扰信号,防止接收机饱和,降低噪声环境中的J/S比值,鉴别真假目标以及提供恒虚警率(CFAR)。为达到这些目的,必须在雷达系统综合与设计阶段就考虑ECCM,并在设计中把它们包括进去,而不是事后再加进去。多年来人们一直在研究雷达ECCM,并取得了很大的进展。但需特别指出的是,特定的ECCM通常是用以对抗特定的雷达ECM的,下表列出了对抗各种雷达ECM的雷达ECCM。
Radar Electronic Jamming Measures (ECCM) are used to weaken or counteract various ECM interferences to the radar. Usually, the radar ECCM avoids the interference frequency, weakens the interference signal entering the receiver, prevents the receiver from being saturated and reduces the noise J / S ratio in the environment, identifying true and false targets and providing CFAR. For these purposes, the ECCM must be considered in the radar system synthesis and design phase and included in the design rather than being added later. People have been studying radar ECCM for many years and made great progress. However, it is important to note that specific ECCMs are usually used against a specific radar ECM. The following table lists radar ECCMs against various radar ECMs.
