Research on Signal Sorting Method Based on Pulse Repetition Interval
Pulse repetition interval(PRI)is an important radar signal sorting parameter,and there have been many studies on PRI jitter and misalignment sorting methods.This paper firstly studies PRI sorting methods such as the time of arrival(TOA)difference histogram method,the traditional PRI transform method,and the modified PRI transform method.In the case of a large number of pulse signal losses,this paper simulates and analyses the PRI sorting ability of the above methods,and the results show that the sorting performances of PRI transform methods are better than the cumulative difference(CDIF)histogram and the sequential difference(SDIF)histogram algorithm.To suppress subharmonics and improve the sor-ting performance of the modified PRI transform method,this paper presents an improved method using the sequence difference(SDIF)histogram method to assist the improved PRI transform method.The simulation results show that the new improved method has a good sorting effect on a large number of pulse signal los-ses.
