摘要：
提出了一种8单元均匀圆阵天线互耦合校正方法。通过采用压缩感知方法,在互耦合效应存在的情况下估计校正信号源的到达角,并确定互耦合系数的迭代初始值,然后通过求解一个优化问题来得到互耦合系数。仿真实验与实测数据结果表明，所提的压缩感知方法能够精确估计校正信号源的到达角,所提方法计算得到的互耦合系数对8单元均匀圆阵天线的校正效果良好。
Abstract:
A mutual coupling compensation method in 8 element uniform circular array is proposed. Firstly, the compressed sensing method is used to determine the direction of arrival (DOA) of the calibration signal source, as well as the initial mutual coupling coefficients. Then the mutual coupling coefficients are obtained by solving an optimization problem. Simulation results show that the proposed compressed method is able to estimate the DOA of the calibration source with a high accuracy and the mutual coupling coefficients obtained by the proposed method are able to calibrate the 8 elememt uniform circular array excellently.
