The Analyses and Improvement of Passive Radar Pulse Pairing Histogram Statistic Method

Based on the mathematics model of pulse pairing histogram statistic method, this paper discusses the ambiguity reason of high-frequency pulse signal pairing using the histogram statistic method, and computer simulation is applied to prove that the extended pulse pairing histogram statistic method can not resolve the ambiguity of high-frequency pulse signal entirely, then this paper gives the method of multilevel extended pulse pairing histogram statistic method to wipe off the false peaks, computer´s simulation proves the valid of ambiguity elimination
