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.
处理器的功能包括：1）测量信号参数，尤其是选定雷达的脉冲重复间隔（PRI）参数。
The functions of the processor are 1) measuring the signal parameters, especially the Pulse Repetition Interval(PRI) of desired signa.
脉冲重复间隔(PRI)分选算法是当前雷达对抗系统分选、识别截获信号的关键技术之一。
Sorting algorithm based on PRI is one of the key technologies to sort and recognize the intercept signal from the current radar countermeasure systems.
