Folding Deinterleaving Algorithm for Multiple Mixed Pulse Trains with Pulse Repetition Intervals

In this paper, a new deinterleaving algorithm for separating pulse signals from a multiple superposed pulse train is presented. We also introduce the current research in radar signal recognition, and point out that the synchronization method used in computing pulse repetition interval has some disadvantages, such as the "double period" phenomenon. It is shown, by a case study and analysis, that the new algorithm is much more efficient for high density pulse signal environment compared with that in synchronized method
