一种基于频域的脉冲信号分选的新方法

A New Method of Pulse Signal Sorting Based on Frequency

提出了一种基于频域的雷达脉冲信号分选方法,新方法打破了以往主分选算法CDIF、SDIF、变换等只考虑分选的局限性,考虑从RF角度进行分选,并综合AOA、PW、PRI等信息进行辅助分析。在仿真试验中,对于复杂雷达信号环境使用新方法进行逐层分选,并依照平面变换技术在RF-TOA平面上显示分选结果,可明显看到新方法能实现对多种PRI调制和RF调制相交叠的情况进行分选,并且算法简单易于实现。

A method of radar pulse signal sorting based on RF frequency is proposed. The new method is mainly based on with the assistance of AOA, and PRI. It overcomes the restriction of traditional sorting methods such as CDIF, SDIF and PRI transformation. According to simulation result in complex radar electromagnetic environment, the new method is implemented step by step. And the results are shown in the RF-TOA plane based on plane transformation technique. It is clear that the new method is simple and easy to realize and good at sorting radar signals of multiform PRI and multiform RF.
