- With regard to two dimensional Direction-of-Arrival (2-D DOA) estimation in sparse array, this paper presents a singular value threshold based estimation of signal parameters via rotational invariance technique (SVT-ESPRIT) algorithm. Firstly, a signal model of DOA estimation based on matrix completion is established which turns out to meet Null Space Property (NSP). Secondly, a full signal array is recovered from a sparse signal array using fixed-point iteration algorithm. Finally, 2-D DOA estimation can be achieved from the recovered signal. The proposed algorithm can reduce the number of array elements and achieve high accuracy of 2-D DOA estimation in sparse array. Computer simulations demonstrate the effectiveness and robustness of the proposed algorithm.
