An algorithm for deinterleaving of radar pulse signals through plane transformation

The paper proposed a new method for periodical radar signal deinterleaving,named matrix matching method.With this method,the radar pulses are mapped into planar matrix via planar transformation.The former deinterleaving methods have the problem of setting the threshold value;moreover,when the signal is dense or sparse,it almost cannot be deinterleaved.This algorithm analyzes the minimal PRI automatically by matching the similar sequences,so it can overcome these problems.Simulation shows that this algorithm can deinterleave the periodic radar signal effectively and has the ability to sort the radar signals of PRI jitter.This new algorithm is fast and easy to realize,and has a broad engineering application prospects.
