Abstract:

This paper presents a new method for two-dimensional (2-D) directionofarrival (DOA) estimation of coherent signals with a special array. This method needs only two orthogonal linear arrays to estimate the 2-D DOA of different users. It uses one of the two linear arrays to pair the 1D DOA which is estimated by the two linear arrays respectively. It constructs a new covariance matrix based on the spatial smoothing method to further resolve the coherence between the two signals. The influence of the coefficient on the DOA estimation is analyzed. The proposed method is validated by computer simulation.

Key words: informatton procesing technology, direction of arrival (DOA), coherent sources, spatial smoothing, two-dimensional, orthogonal
