摘　　要：机载雷达告警接收机作为一种雷达侦察设备,主要用于对高威胁雷达目标进行识别和告警,而识别的前提是信号的分选。针对传统告警接收机普遍存在增批、虚警的问题,提出了基于数字雷达告警接收机的信号分选与识别方法,介绍了其工作流程和雷达信号的时域模型,对多通道雷达信号分选和识别实现方法进行了阐述,通过试验验证了该方法的有效性。As a kind of radar reconnaissance device,the airborne radar warning receiver（RWR）is mainly used to identify and warn to the high threat radar targets,however the premise of identification is signal sorting.Aiming at the ubiquity problems of batch increasing and false alarm in traditional warning receiver,this paper present the signal sorting and identification methods based on digital radar warning receiver,introduces its working flow and time-domain model of radar signal,expatiates the realization methods of multi-channel radar signals sorting and identification,validates validity of the method through the experiment.
