Direction of arrival algorithm which MUSIC and ESPRIT methods use in many case an antenna element than signal number. Such algorithm has known super resolution in direction of arrival estimation for position target. These algorithm are estimation direction of arrival from adaptive array antenna response vector peak in noise subspace eight spectrum to divided signal subspace and noise subspace, and estimates for signals by rotational matrix. These method are shortcoming of estimation angle because of many sampling and eigen vector. In this paper, we study about drawback of adaptive array antenna using linearly constrained Minimum Variance. Spilt Polarity Transformation-LCMV obtains SPT matrix using constrain matrix as steering vector of incident angle. SPT matrix can estimate desired signal because of covariance matrix which remove desired signal and coherent signal.
