A Novel Deinterleaving Algorithm of Radar Pulse Signal Based on DSP

A deinterleaving algorithm of radar signal based on DSP is presented in this paper, which is according to the structure of the deinterleaving system, characteristics of PDW (Pulse Descriptor Word) and histogram method. The threshold determination, accumulation of PRI (Pulse Repetition Interval) and others in the algorithm applied in different fields are introduced in detail. The experimental results and comparison with PRI transform method show that the algorithm in the paper does not only achieve the excellent deinterleaving performance in the mixed signal of normal pulses, staggered pulses and jittered pulses with high density of 200 thousand pulses per second from the same direction, but also do well with the capability of real-time processing and robustness.
