The optimized weight is arrived by weighted the minimum variance distortionless response weights of these samples with their post probabilities. In addition, the samples with little post probabilities will be resampled and it improves the robustness of beamforming effectively.

在该算法中期望信号的波达方向被看成一个由若干样点组成的随机变量，利用后验概率对这些样点的最小畸变响应波束成形权值进行加权来取得优化的权值，并对小概率样点进行重采样，有效地提高了波束成形系统的鲁棒性。

The beamforming is an important measure of the orientation estimation in theunderwater sound positioning. The Generalized Correlation Beamformer isstudied and the algorithms of FIM and WFIM(WeightedFourier Integral Method) are given. In most circumstances, the performance of these two algorithms is better than Delay-Sum Beamformer. The MVDR(MinimumVariance Distortionless Response) adaptive beamformers are investigated in element andbeam domain. The research results show that the beam-domain MVDR algorithm notonly increases the resolution, but also saves computer when using it to aim orientationestimation.
