宽带雷达对抗侦察数字接收机具有较宽的瞬时频率覆盖特性和较高的截获概率，并能处理同时到达的多个信号。

Wide frequency spectrum can be received and high probability of intercepting can be got and the simultaneously attend signals can be processed by wide band radar EW reconnaissance digital receiver.

最后，分析了参差脉冲重复间隔步进频率信号的低截获概率特性。

Finally, the Low Probability of Intercept (LPI) of SPRI-SF radar signal is analyzed.
