| 摘 要： | PRI变换是一种基于脉冲到达时间的信号分选方法,由于该算法能够有效抑制真实PRI的谐波,近年来受到越来越多的关注。首先讨论了相位因子的作用,揭示了相位因子是进行变换谱峰值累积的关键;接着通过理论分析指出了PRI变换法的局限和适用的PRI类型;最后仿真分析了该方法对分选过程所面临的信号环境的适应性。理论及仿真分析结果可作为工程应用的参考依据,具有一定的实用价值。

| Abstract: | Since it can suppress PRI harmonics efficiently,PRI transform,a DTOA-based algorithm,is widely researched in radar signal sorting.Phase factor is firstly discussed,and its effect in PRI spectrum accumulating is revealed;then both the limitations of PRI transform and its adapted PRI types are analyzed theoretically.Finally,the performance of PRI transform to real signal environment is given by computer simulations.Both theoretical analysis and simulation results can be used as engineering reference. |
