摘要
在运动阵列存在幅相误差和阵元位置未知的条件下,提出了一种基于子空间方法的阵列幅相误差校正和阵元位置估计方法。该方法要求一个方位已知的近场校正源。计算机仿真结果表明,该校正方法可有效地估计出阵列参数。
Under the condition that the moving array has amplitude/phase errors and the location of the array source is unknown, a new method is proposed in this paper for calibrating the array amplitude/phase errors and estimating the location of the array source based on subspace approach. This method requires a nearfield source whose azimuth is known. Simulation results show that the new method can estimate the array parameters effectively.
