Deinterleaving method of complex staggered PRI radar signals based on EDW fusion

Abstract

Most of the existing pulse deinterleaving algorithms cannot deal well with complex staggered pulse repetition interval (PRI) radar signals which have >10 stagger levels. To solve this problem, a deinterleaving method based on emitter description word fusion is proposed here. The sub-PRIs of a complex staggered PRI signal are detected by applying histogram statistics with overlapped PRI bins, then a data fusion is carried out to distinguish between complex staggered PRI signals and jittered PRI signals according to their characteristics in the set of PRI values. Furthermore, a general deinterleaving framework for PRI agility complex signals including jittered PRI signals, complex staggered PRI signals, and sliding PRI signals is also presented. Finally, experiments with collected real data demonstrate that the authors’ proposed method is very effective in deinterleaving of complex staggered PRI signals.
