线性阵相位误差校正约束条件性能分析

The Performance of Phase Error Constraints for Linear Array Calibration

本文首先从信号模型出发分析了线性阵相位误差在信号源方向未知时的不可校正性，与所采用的校正方法无关。对为求解相位误差而构造的不同约束条件进行了统计性能分析，给出了性能的显式表达式。计算机仿真结果验证了其分析正确性。

Based on the sigrial model, being not related to calibration method , the uncalibrability of thephase error of linear array is analyzed in this paper firstly. Then,the performance of the constraints which areconstructed to ealibrate the phase error are analyred. The formulas of the constraints' performance are given .Computer simulation results show the correctness of analysis .
