本文针对增益误差对空间谱估计性能的影响，提出了一种基于算术平均值的平滑校准方法，并将它与其它核准方法进行了比较，理论分析和实验仿真均表明了本文提出的方法具有更好的稳健性能和校准效果。
In this paper, aiming at the effect of gain error on spatial spectral estimation performance, a smoothing calibration method based on arithmetic average is proposed and compared with other approved methods. Both theoretical analysis and experimental simulation show that the proposed method has more Good robustness and calibration.
