Fast Active Error Calibration Algorithm for Array Chanel Uncertainty

  • 摘要: 针对阵列通道不一致性引起的幅相误差校正问题,基于多级维纳滤波器(MSWF),该文提出幅相误差快速校正的简化的多级维纳滤波器(SMSWF)算法。SMSWF算法利用校正源的方位和波形信息对阵列幅相参数进行估计,无需估计协方差矩阵和进行特征值分解,大大地减小了计算量,且具有与特征分解方法相同的幅相参数估计性能。研究发现,单个信源入射到阵列且信源波形已知时,SMSWF算法获得的信号子空间等价于特征分解法得到的信号子空间,这表明SMSWF算法能够替代特征分解法,从而极大减小基于特征分解法的信号处理方法的计算量。大量计算机仿真和消声水池试验验证了SMSWF算法的优越性能。
