摘要

提出了一种截断傅立叶级数来近似阵列的响应。基于该模型和校准程序，推导了对数似然函数。采用数值电磁法计算了天线阵列的响应。在此基础上进行了标定仿真。直接最大化对数似然函数允许全方位校准与低误差，只需要40个源。

Array calibration by Fourier series parameterization: stochastic maximum likelihood solution

A truncated Fourier series is proposed to approximate an array's response. Based on this model and a calibration procedure, the log-likelihood function is derived. An antenna array's response was computed using a numerical electromagnetic method. Based on this array response a calibration was simulated. Direct maximization of the log-likelihood function allowed for full azimuthal calibration with low error and required only 40 sources.<>
