Abstract

In this paper we propose a DOA estimation method by combining propagator method (PM) algorithm for co-prime L-shaped arrays. The array contains two uniform L-shaped arrays with the minimum inter-element spacing larger than the half-wavelength, which will cause phase ambiguity. Utilizing the co-prime relationship between each decomposed array can eliminate phase ambiguity. With PM algorithm, we avoid peak searching and eigenvalue decomposition of received signal covariance matrix, which have a low computational complexity. Compared with the typical L-shaped arrays which have the same amount of array elements, the proposed method for co-prime L-shaped arrays have a better 2D-DOA estimation performance and a low computational cost. Extensive simulation results demonstrate the effectiveness of the proposed method.
