Abstract

In array processing, super-resolution eigenstructure direction-of-arrival (DOA) estimation methods are known to be sensitive to sensor gain, phase and position perturbations. This paper presents a method to calibrate sensor gain, phase and position errors, simultaneously, which is based on three or more disjoint sources in known directions. The method can be applied to arbitrary arrays and low SNR cases. Computer simulations are given to demonstrate the performance of the calibration method.<>
基于传感器增益、相位和位置扰动的DOA估计
在阵列处理中,超分辨率特征结构到达方向(DOA)估计方法对传感器增益、相位和位置扰动非常敏感。本文提出了一种基于已知方向上三个或多个不相交源同时校准传感器增益、相位和位置误差的方法。该方法适用于任意阵列和低信噪比情况。通过计算机仿真验证了该标定方法的有效性。
