摘　　要：根据频率捷变信号的特点,分析了几种侦察体制下接收频率捷变信号需要的中频带宽、扫描步进频宽和截获时间,给出了对频率捷变信号侦察的可行性方案.According to the characteristic of the frequency agile signal, the BW of intermediate frequency, scanning step width of frequency and time of capture are analyzed when the frequency agile signal is processed in several reconnaissance systems. The feasible schemes to reconnaissance of the frequency agile signal are provided.
