摘　　要：通过研究声矢量传感器阵列中高效的运动目标到达角(DOA)跟踪算法,提出一种声矢量传感器阵列中基于紧缩投影近似子空间跟踪(PASTd)的DOA跟踪方法。该方法利用PASTd算法进行声矢量传感器任意阵的DOA跟踪,其快速收敛的特点可以降低运算复杂度。同时,其角度跟踪的均方根误差(RMSE)性能优于常用的PAST算法。仿真结果验证了该算法的有效性。Target tracking algorithms for moving targets in acoustic vector-sensor array are investigated and an efficient Direction Of Arrival(DOA) tracking algorithm for acoustic vector-sensor array based on Projection Approximation and Subspace Tracking of deflation(PASTd) is proposed. The proposed algorithm uses PASTd method to track the DOA of received signals for acoustic vector-sensor arbitrary array, and owing to the fast convergence features, it holds the properties of lower computational complexity. Furthermore, the proposed algorithm outperforms the PAST method in terms of angle tracking accuracy. A series of simulation results verify the effectiveness of the algorithm.
