摘要

本文提出了一种新的高分辨率谱分析法——最小对称发散度（MSD）谱分析法。该方法把最小交叉熵谱分析法（MGEM）所使用的最小非对称发散度准则修改为MSD准则

使得它利用了先验谱中含有的全部平均鉴别信息

从而给出了性能优于MCE谱的谱估计。本文还开发了MSDM的非迭代快速算法

该算法把MEM算法拓广应用于计算随机信号的MSD谱

因此它具有与MEM算法相同的计算有效性。计算机模拟例证了本文开发的MSDM及其快速算法的正确和有效

也例证了MSD谱的性能明显优于MCE谱。

Abstract

A new spectral analysis method with high resolution minimum symmetric divergence spectral analysis method （MSDM） which uses MSD principle as optimization criterion to exploit the total average discrimination information and to make MSD spectrum better than MCE spectrum is developed. With MEM being generalized to compute the MSD spectrum

a fast and noniterative MSDM algorithm which is as effective as fast MEM algorithm in computation is developed too. Computer simulations which demonstrate that the developed method and its fast algorithm are correct and efficient are illustrated.
