摘　　要：随着雷达用户越来越多,对雷达信号的监测和深度分析越来越重要。尤其是部分无线电业务受雷达业务干扰时,考虑到雷达业务的重要性和敏感性,不能轻易开关机做实验来确认是否为雷达产生的干扰。为此,结合雷达使用的频率以及传播特性从雷达信号深度分析的角度,着重分析了不同雷达的相关特点以及当雷达受干扰时的干扰分析,通过分析对干扰接收机的设置技巧,准确还原信号的频谱、时域、瀑布图等显示,获取目标雷达信号的时域特征、频域特征、幅度变化规律特征等。Nowadays,more and more radar frequency resource utilized and it is more and more important to monitor and analyze radar signals.Especially when some radio services are interfered by radar services,considering the importance and sensitivity of radar services,it is not easy to switch on and off to do experiments to confirm whether the interference is caused by radar.Therefore,combining with the frequency and propagation characteristics of radar,from the perspective of radar signal depth analysis,this paper focuses on the analysis of the correlation characteristics of different radars and the interference analysis when the radar is interfered.By analyzing the setting skills of the radio receiver,the spectrum domain,time domain and the waterfall diagram of the radar signal are accurately tested to obtain the time-domain and frequencydomain characteristics of the target radar signal.
