| 摘 要： | 介绍了改进的MUSIC算法在矢量水听器阵波达方向估计中的应用,并描述了该算法的原理及应用过程.计算机仿真的结果表明,改进的MUSIC算法既能够有效地估计出独立信号源的DOA,也能有效地估计出相关信号源和相隔比较近的小角度差信号源的DOA,从而证明了这种改进MUSIC算法的合理性.

| Abstract: | MUSIC algorithm can't estimate coherent signals and adjacent signals with small angle difference.In this paper a MMUSIC(Modified Multiple Signal Classification) algorithm for the DOA estimation in Linear Array of Acoustic Vector-sensors is presented.The operation principles of this algorithm are described in detail.MMUSIC can estimate the DOA of coherent signals and adjacent signals with small angle difference.The simulations have proved the effectiveness of this new modified MUSIC algorithm. |
