Analysis of influence of repeated frequency combined pulse interference on radar signal sorting
In order to improve the active anti-sorting ability of radar signal,the algorithm characteristics of histogram method and PRI transform method are analyzed from the point of view of weakening the sorting perfor-mance of the sorting algorithm to the pulse repetition interval,and then the pulse interference signal is designed reasonably under certain constraints.Finally,the simulation verification is conducted,and the results show that the interference signal can change the statistical property of the sorting algorithm to the real radar repeated frequency,causing the reconnaissance system to produce errors or false radar signal repeated frequency,so as to realize the electromagnetic protection of high-value targets.
