将阵元域高分辨加权子空间拟合算法（ＷＳＦ算法）推广到了波束域中，利用声系统接收基阵波束输出信息估计目标方位．由于波束输出可以看作是，一个阵元数为波束个数的虚拟阵的阵元输出，而在大多数的水声系统中，参与确定某个来向的信号方位的波束数通常远小于阵元数，从而算法的运算量得以大大降低。针对某水声系统接收基阵波束输出所作的计算机仿真结果表明，波束域ＷＳＦ算法应用到实际的水声系统时，可以保持其在阵元域中估计目标方位的优越性能。
The array element high-resolution weighted subspace fitting algorithm (WSF algorithm) is extended to the beam domain, and the target azimuth is estimated by using the acoustic system to receive the array beam output information. Since the beam output can be regarded as an array element output of a virtual array with an array element number of beams, in most underwater acoustic systems, the number of beams involved in determining the orientation of a certain direction is usually much smaller than that of the array The number of elements, and thus the amount of computation of the algorithm is greatly reduced. The computer simulation results of a certain underwater acoustic system receiving array beam output show that the beam domain WSF algorithm can maintain the superior performance of estimating the target azimuth in the array domain when applied to an actual underwater acoustic system.
