New method for DOA estimation of narrow band and coherent sources with highly accurate based on subspace method and limited sensor array

In this paper two methods are presented for DOA estimation of narrow band and coherent signals. Advantages of this method with compare to another methods are Simple calculation, highly accurate for low signal-to-noise-ratio (SNR) and low requirement sensor array. this method is used for coherent signal and also it can used for know algorithms such as MUSIC, Root-MUSIC, ESPRIT which just applied for DOA estimation of narrow band and noncoherent signals. main purpose in the presented methods is calculation of mean cross correlation vectors between receiver signals on sensor array and out of them. In this paper have been compared the presented method to FBSS and FOSS method together by Matlab.
