The sorting of radar pulse signal based on plane transformation

Pulse repetition interval (PRI) is an important parameter in radar signal sorting. In this paper plane transformation technique is applied to radar signal sorting. Firstly we derive the plane transformation characteristic curve of a periodic signal, followed by an improved extraction algorithm. Simulation results show that the extraction algorithm transforms the characteristic curve correctly after automatic detection. This method can be applied to the fixed PRI, mixed PRI and random jitter PRI pulse train.
