| 摘 要： | 基于线性约束最小方差(linearlyconstrainedminimumvariance,LCMV)波束形成原理,根据贝叶斯估计理论,提出了一种基于加权的波束形成方法。该波束形成方法能够很好地克服LCMV波束形成对期望信号DOA误差特别敏感的弱点。仿真试验表明,该方法性能稳定,对期望信号DOA误差具有很好的稳健性。

| Abstract: | Based on the principle of linearly constrained minimum variance (LCMV) adaptive beamforming, an adaptive beamforming method by using Bayesian posterior probability weighted sum is proposed in terms of the Bayesian estimation theory. The method is developed to improve robustness to pointing error and overcome the shortcoming of LCMV beamforming's sensitivity to pointing error. The results of simulation indicate that the performance of the proposed beamforming method is robust to the pointing error. |
