摘要

本文提出一种修正的ＳＣ ＳＳＦ方法．该方法适用于宽带和窄带源，不仅可解决循环相关源的问题，而且具有更好的噪声抑制特性．用蒙特卡洛试验证实该方法噪声抑制性能优于ＳＣ ＳＳＦ，并具有对相同循环频率的多个循环相关源进行ＤＯＡ估计的能力

Abstract

In this paper

we propose a modified SC SSF（spectral correlation signal subspace fitting）method to estimate DOA of coherent narrow band or wide band signals

while the advantage of SC SSF method still rematins.Monte Carlo trials demonstrate that the noise suppression of this method is superior to that of SC SSF

and can be used to multi cyclic correlated signals with same cyclic frequency.
