A radar signal sorting algorithm based on PRI

Based on the PRI transform method, this article has found a radar signal sorting algorithm which aims at sorting those received radar pulse signals and recognizing their classes. Firstly, this method will screen those received radar pulse signals through the PRI transform method. And then, for the different kinds of radar pulse signals, it will choose different methods for sorting. When it comes to the problem of poor recognition of PRI staggered radar signals by traditional radar signal sorting method, the author uses a combined sorting based on the PRI transform method and the SDIF algorithm to identify the PRI staggered radar signals by setting the judging conditions. Finally, the algorithm has been simulated, of which the result show that the algorithm can successfully sort out different PRI radar signals.
