摘要
Abstract
As an important part of the electronic reconnaissance system,radar signal sorting becomes particularly important in the increasingly complex electromagnetic environment.A signal sorting method based on sliding window correlation detection is proposed in this paper.In the complex electromagnetic environment,the long-range radar signal detected by over-the-horizon reconnaissance is mainly its main lobe beam scanning signal.In a processing cycle,the number of radar pulses of interest is often very small.Relying on the traditional signal sorting process,it is difficult to obtain the correct signal sorting results in a single processing cycle.Aiming at such problems,a method of dynamic sliding window accumulation of input Pulse Description Word(PDW)during processing is proposed.By using the continuity of the same radar signal in multiple main lobe scanning cycles,the PDW obtained by reconnaissance are accumulated by dynamic sliding window,and the PDW data accumulated in the sliding window is processed each time.Through simulation verification,this method can achieve a good sorting effect for over-the-horizon long-range radar signals.关键词
