摘　　要：研究了将数字波束形成和超分辨测向相结合的方法。比较了波束形成算法和阵元空间超分辨测向算法的性能，介绍了波束空间MUISC算法的基本原理。仿真证明波束空间的超分辨算法具有计算量小、测向分辨力高和充分利用阵列孔径的特点。The algorithm of combining digital beam-forming and high-resolution methods is researched. The performance of beam-forming and classical MUSIC method is compared; the beamspace MUSIC algorithm is introduced in this paper. The simulation results show that the DOA estimation algorithm based on beam-space has better performance such as less executing time, higher resolution and efficient array aperture usage.
