摘　　要：从引信系统信号处理角度出发,介绍了各种谱估计的方法,着重分析了现代谱估计的理论、方法和应用;讨论了作为参数模型谱估计中经典的方法AR谱分析方法和非参数谱估计的典型方法MUSIC法和特征向量估计法的处理过程,并对各种谱分析进行了比较,指出用现代谱分析处理引信系统探测信号的优点。Form the point of view of processing the signal detected by the fuze system , multiform power spectrum estimate methods are introduced in brief. Theory, method and application of modem power spectrum estimate are analyzed in detail. The processing course of AR power spectrum estimate method which is classic method in parameter model power spectrum estimate method and the course of MUSIC power spectrum estimate method and the eigenvector method which are classic methods in non-parameter model power spectrum estimate method are discussed. These power spectrum estimate methods are compared. In the end the advantage of processing the signal detected by fuze system is explained.
