摘　　要：为提高矢量阵方位估计能力,论文给出了一种改进算法。这种算法利用解析振速,重构了矢量阵接收数据模型,从而得到一种新的阵列流形形式。然后利用MUSIC算法对该阵列流形的矢量阵数据进行方位估计。理论分析表明,此种阵列流形具有较好的角度分辨力,并且同样具有一定的抗左右舷模糊能力。最后的仿真与湖试证明了论文算法较好的角度估计性能。With the purpose of improving bearing estimation of vector sensor array, this paper gives an improved algorithm.This algorithm uses analytic velocity to construct a received data model of vector sensor array, so as to obtain a newarray manifold. Then MUSIC algorithm is used to get bearing estimation The theory analysis could prove this array manifoldmay have a better angle distinguish-ability,and a certain extent left-right suppressing. At last, simulation and lake experimentprove better bearing estimation performance of this algorithm.
