Research into A Radar Signal Sorting Method Based on PRI Transform

阐述了雷达信号分选的参数和方法,论述了直方图算法、脉冲重复周期(PRI)变换法的原理,研究了PRI变换法及其改进算法的性能,利用Matlab软件进行仿真实验,验证了改进后的PRI变换法能克服PRI抖动带来的信号分选困难,为下一步建立雷达对抗分选模型和采用主分选算法提供了参考依据。

This paper expatiates the parameters and methods of radar signal sorting, discusses the principle of histogram algorithm and pulse repetition interval （PRI） transform algorithm, studies the performance of PRI transform algorithm and its improved algorithm, uses Matlab software to perform simulation experiment,validates that the improved PRI transform algorithm can overcome the signal sorting problem due to PRI signal jittering,which provides the reference basis for build- ing the sorting model of radar countermeasure and adopting main sorting algorithm.
