Abstract

The problem of two-dimension coherent direction of arrival (DOA) for uniform planar array is investigated in this paper. The signals propagate over multipath channel, which thus leads to the coherent source. The traditional two-dimension direction of arrival (2D-DOA) estimation algorithm fails to work for the coherent source. In this paper, we will propose a coherent DOA estimation algorithm for uniform planar array, which uses the characteristic of Toeplitz matrix to restructure the covariance matrix, and use rotational invariance technique to realize the 2D-DOA estimation. The validity and performance of the algorithm can be verified by simulations in this paper.
