| 摘 要： | 基于声矢量传感器阵列的二维来波方向估计是水声通信的关键技术,但阵列增益的不一致性将影响来波方向估计性能.基于子空间分解,提出一种阵列增益和来波方向的联合估计算法,其中来波方向利用旋转不变性求解,阵列增益利用子空间正交性求解.来波方向和阵列增益以迭代方式求解.仿真结果显示了算法的有效性.

| Abstract: | 2-dimensional(2D)Direction-of-Arrival(DOA)estimation based on acoustic vector-sensor array is an important issue in underwater communication.The gain uncertainty of the array will degrade the accuracy of DOA estimation.The gain response is considered as part of the parameter estimation problem and propose an eigenspace based joint DOA and gain estimation algorithm.The arrival angles are estimated based on the shift invariance property and the gains are estimated based on the orthogonality of different subsp... |
