Processing the matrix signals of vector sensor is critical to the research on engineering application of vector matrix.However

such processing amount requires massive computation.Aiming at this problem

a new modified MUSIC algorithm（MMUSIC） based on vector matrix is introduced to solve such issue.The method reduces computation amount by applying the Wiener Filter in MUSIC algorithm to skip decomposition of eigenvalues.The method of vector sensor uniform linear array（ULA） is adopted to study the performance of the modified algorithm.The simulation and experiment verify the effectiveness of such new MMUSIC algorithm

showing that the new MMUSIC algorithm can clearly distinguish the coherent signals

and is superior to the original MMUSIC algorithm.
