DOA Estimation for Sparse Linear Array With Position Error

Based on the parametric sparse representation technology, a DOA estimation method for sparse linear array with position error is proposed in this paper. In this method, the first-order linear error of the array element is taken as the core parameter to construct a parametric perception matrix, and then the error parameter and the target angle vector are jointly solved by the proposed parametric orthogonal matching pursuit algorithm. Simulation results show the effectiveness of the proposed method.
