摘要
现代雷达普遍使用相参信号,该特征可以作为信号分选的依据之一,从而减少现有分选方法的“漏批”问题。文中在分析相参与非相参信号频谱的基础上,研究了初始相位差对频谱的影响,采用与重构脉冲信号频谱主峰幅度匹配的方法,实现相参信号的分选。与同类分选方法相比,在考虑侦察设备参数测量误差的情况下该方法仍然有效,同时减少了运算量,最后通过仿真验证了方法的有效性。
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.
