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.
