在已有文献介绍过的几种阵列校正算法中.仅有少数算法就阵列由于互感耦合、传感器位置误差以及阵列信道失配的共同作用所产生的信号到达方向估计误差问题做过讨论.通过广义阵列参数化方法来描述标称阵列和实际阵列之间的偏差.阵列校正问题就可以被看作是校正矩阵和传感器位置估计问题.这种阵列校正算法通过一组可测定的方向矢量来估计传感器位置和校正矩阵.该方法的用途和特性通过模拟实验加以说明.
Of the several array correction algorithms that have been described in the literature, only a few algorithms discuss the estimation error of the arrival direction of the array due to the interaction of the mutual inductance coupling, the sensor position error and the array channel mismatch. Array parameterization method to describe the deviation between the nominal array and the actual array.An array calibration problem can be considered as a calibration matrix and sensor position estimation problem.The array calibration algorithm through a set of measurable direction vector to estimate the sensor Location and correction matrix.The purpose and characteristics of this method are illustrated by simulation experiments.
