Abstract

In this paper, we discussed the problem of two-dimensional (2D) direction of arrival (DOA) estimation for non-uniform L-shaped array, and for this, a low complexity multiple signal classification (MUSIC) algorithm is proposed.The proposed algorithm uses two one-dimensional searches to achieve the joint estimation of 2-dimensional DOA so as to avoid the high computational cost within 2D-MUSIC algorithm.And the angle estimation performance is very close to the 2D-MUSIC algorithm.The proposed algorithm achieves a good balance between the estimation accuracy and complexity.
