Abstract:

This paper analysis the theory and algorithm of the high resolution spatial spectrum estimation,and gives a realization method of dual channel receiver in the spatial spectrum estimation,it is based on the single channel receiver theory in the spatial spectrum estimation.The algorithm for estimating the covariance matrix of the array sensor outputs using a weight perturbation technique is presented.

Key words: spatial spectrum estimation;DOA;dual channel receiver;weight perturbation
