A Frequency Domain Sorting Method of Coherent Radar Pulse Signal
Modern radar generally uses phase-coherent signal,which can be used as one of the basis for signal sorting,so as to reduce the problem of"missing batch"in existing sorting methods.In this paper,based on the analysis of the frequency spectrum of coherent and non-coherent signals,the influence of the initial phase difference on the frequency spectrum is studied,and the method of matching the main peak amplitude of the reconstructed pulse signal spectrum is adopted to realize the sorting of the coher-ent signal.Compared with similar sorting methods,this method is still effective when considering the parameters measurement error of reconnaissance equipment,and reduces the amount of computation in addition.Finally,the effectiveness of the proposed method is verified by simulation.
