Radio frequency stealth radar anti-sorting signal design method and system based on pulse group agility

The embodiment of the invention provides a radio frequency stealth radar signal design method and device based on pulse group width agility, and the method comprises the steps: setting two groups of radar signals, enabling the difference between PRI central values of the two groups of radar signals to be more than A times, and enabling A to be a positive integer; in each set of radar signals, a signal variation is set within a predetermined percentage of a PRI center value. By adopting the method, the RWR main sorting algorithm can be effectively resisted, and the target of radar sorting resistance is achieved. 本说明书实施例提供了一种基于脉组宽捷变的射频隐身雷达信号设计方法及装置，其中，方法包括：设置两组雷达信号，使两组雷达信号的PRI中心值相差A倍以上，其中，A为正整数；在每一组雷达信号中，设置信号变化量在PRI中心值的预定百分比以内。采用本发明能有效对抗RWR主分选算法，实现雷达抗分选的目标。
