Research of Modified MUSIC Algorithm based on Vector Matrix

摘要：

Processing the matrix signals of vector hydrophone was critical to the research on engineering application of vector matrix. However, such processing required massive computation. Accordingly, a vector matrix based modification of MUSIC algorithm was introduced to solve such issue. The said modification lowered computation amount by applying the Wiener Filter in MUSIC algorithm to skip decomposition of eigenvalues. The method of vector hydrophone Uniform Linear Array (ULA) was adopted to test the performance of the modified algorithm. The computer simulated outcome has verified the effectiveness of such modified MUSIC algorithm, showing that the modified MUSIC algorithm can clearly distinguish the coherent signals, and is superior to the original music algorithm.
