针对均匀圆阵存在一般阵列误差(如阵元的幅相误差和安装位置误差等)的情况,提出了多个信号的波达方向和多普勒频率估计方法.直接利用均匀圆阵的阵列流形,采用波达矩阵法估计各个信号的多普勒频率.由一般阵列误差的统计特性构造加权矩阵,采用加权总体最小二乘法估计各个信号的波达方向.此方法具有鲁棒性强等特点.计算机仿真证明了此方法的有效性.“,”The problem of estimating direction of arrivals (DOA) and Doppler frequency for many sources is considered in the presence of general array errors (such as amplitude and phase error of sensors, setting position error of sensors). Adopting direct array manifold in a uniform circular array (UCA), the estimation of Doppler frequency can be obtained by DOA matrix. Based on analyzing the statistic characters of general array errors, the estimation of DOA can be obtained by Weight Total Least Squares. Numerical results illustrate that the estimator is robust to general array errors and show the capabilities of the estimator.
