Self Calibration of Mutual Coupling for Dual Uniform Circular Array

摘要

摘要: 该文基于双圈均匀圆形阵列，提出一种互耦自校正算法，对圆阵内部和圆阵之间的互耦进行了同时校正。算法利用双圈均匀圆阵特殊的互耦矩阵特性，对角度信息和互耦系数进行解耦合，用较少的计算量依次估计出信号角度和互耦系数，完成级联估计。算法减少了搜索维数且无需互耦系数矩阵的任何先验信息，也不需要额外的辅助校正源，简单易实现。理论分析和仿真结果均表明所提算法精度高、分辨力强，可以有效地解决双圈均匀圆阵的互耦问题。

Abstract: Based on the dual uniform circular array, a self-calibration algorithm is proposed in the presence of mutual coupling, which can calibrate the mutual coupling in circular array and between two circular arrays at the same time. The algorithm utilizes the special mutual coupling matrix characteristic of dual uniform circular array to decouple angle information and mutual coupling coefficients. With less amount of calculation, the signal angle and the mutual coupling coefficients are estimated in turn. Finally, the cascade estimation is completed. The algorithm reduces the dimension of searching without any prior information about mutual coupling coefficient matrix and need not extra auxiliary source. So it can be easily implemented. Theory analysis and simulation results illustrate that the new algorithm has high precision and resolution, hence, it can effectively solve the problem of mutual coupling for the dual circular array.
