| 摘要: |
| 针对同时存在通道幅度相位不一致与阵列互耦的均匀直线阵列，提出了一种采用模拟退火算法的阵列模型校正方法。该方法使用多个辅助信源分时工作，
根据子空间基本原理构造目标函数，采用模拟退火算法对幅相误差矩阵及互耦矩阵进行估计。利用该方法对均匀直线阵进行了计算机仿真与实测实验，仿真及实验结果证明了该方法是有效可行的。 |

| Abstract: |
| A method of calibrating the channel uncertainty and mutual coupling of uniform linear array is presented, which is based on simulated annealing algorithm. It used multiple calibration sources working at different time. According to the principle of signal subspace, the target function was constructed. Then, by using simulated annealing algorithm, the gain and phase error matrix and mutual coupling matrix were estimated. Finally, computer simulation and experiment result demonstrates the efficiency of this method. |
