To improve the resolution of direction estimation of circular vector sensor array, a new algorithm based on VTAMVDR is used in circular vector sensor array signal processing. Circular vector sensor array time-domain analysis MVDR algorithm is proposed. Studied the principle and process flow of circular vector sensor array time-domain analysis MVDR algorithm. Compared the beam width and resolution capability of circular vector sensor array time-domain analysis MVDR with circular vector sensor conventional beamforming algorithm. Theoretical analysis and computer simulations show that the proposed algorithm is more effective in improving resolution of multiple targets than the traditional algorithm.%为提高矢量圆阵的方位估计性能,将VTAMVDR(MVDR based on Time-domain Aanalysis signals of Vector Sensor)应用在矢量圆阵中,提出矢量圆阵时域解析MVDR算法,研究了矢量圆阵时域解析MVDR算法的原理及实现流程,然后通过仿真分析对比矢量圆阵时域解析MVDR算法与矢量圆阵常规波束形成的波束宽度、方位估计性能和分辨率.仿真结果表明,矢量圆阵时域解析MVDR算法方位估计性能和多目标分辨能力优于常规波束形成算法.
