针对均匀圆阵设计了一种新的互耦和通道幅相不一致性参数联合估计方法。该方法只需一个信号源和两次不同入射方向的试验就可以完成标定。试验的方向不需要事先校准。首先,在离散傅里叶变换(DFT)波束空间中,利用一种新的解耦技术将两种参数解耦为一个线性方程。然后,根据互耦参数的对称性设置新的目标函数。最后,利用一些先验方向信息,通过有限的角度搜索可以估计所有的参数。仿真结果验证了该方法的有效性和鲁棒性。
A new robust method is designed to estimate mutual coupling and channel gain/phase inconsistency parameters for a uniform circular array (UCA) jointly. It only needs a single signal source and two trials with different impinging directions to complete the calibration. The directions of the trials do not need to be calibrated beforehand. First, the two kinds of parameters are uncoupled into a linear equation in discrete Fourier transform (DFT) beam space by a novel decoupling technique. Then, a new object function is set according to the symmetry of the mutual coupling parameters. Finally, with some prior directional information, all the parameters can be estimated through a limited angular search. Simulations verify the effectiveness and robustness of the proposed method.
