摘　　要：针对阵元数一定时大型面阵均匀布阵易产生分辨力与模糊的矛盾问题,提出了一种基于稀布降维的波达方向高分辨估计方法。该方法极大的降低了运算量,同时保持了高分辨的测向精度,较大的改善了角度分辨率。计算机仿真证明了该方法的有效性和可行性。To a large uniform planar array with fixed number of elements, there is conflict between resolution and angular ambiguity. In order to solve these problems, a novel direction of arrival （DOA） estimation algorithm based on sparse array dimensions descending is presented. The algorithm can significantly reduce computational load, meanwhile obtain high resolution DOA and improve angular resolution. Simulation results verify the efficiency and feasibility of the algorithm.
