摘　　要：分析了线性调频码、非线性调频码、二相码+非线性调频组合码等多种码型的性能,结果表明组合码型是一种较为理想的码型,可为解决编队同型搜索雷达抗同频干扰问题提供参考。This paper analyzes the performance of several codes such as linear frequency modulation code, nonlinear frequency modulation code,two-phase code ＋ nonlinear frequency modulation com- bined code,etc. The result shows that the combined code is the relatively perfect code, which can provide the reference for the solution of anti-common-frequency interference among the same type search radars in the formation.

关 键 词：线性调频 非线性调频 互相关 自相关
