Abstract

Abstract

In light of difficulties in detecting stable Pulse Repetition Interval (PRI) sequence and estimating its PRI in interleaving pulse stream, a fast detecting method based on plane transformation is proposed to solve the above problems. By one time-domain transform, the Periodic Graph of Plane Transformation Point trace (PGPTP) mapping pulse sequence with stable PRI is formed via the presented method performing integer remainder operation on pulse Time Of Arrival (TOA) over plane width. According to the differences in pattern of PGPTP got previously, pulse sequences with stable PRIs interleaved in TOA can be distinguished, and then the stable PRIs are got with point trace longitudinal deployment period and plane width and are therefore used to accurately deinterleave such sequences in dense pulse stream. Simulation results show that this method is valid and possessed of advantages such as high efficiency and practical applicability, etc.
