通过理论分析强馈宽带相控阵天线通道相频特性,提出了一种频点内插快速校准法,在满足校准精度要求的前提下,可通过最小化测试采样数据求出频带内全部数据,解决了宽带相控阵天线逐点校准法时间长的缺点,大幅提高强馈宽带无源相控阵天线校准效率,同时该方法也适用于通道相频特性具备平坦或近似线性特性的相控阵天线校准,因而有较高的应用价值。

In this paper, a fast frequency interpolation method is proposed through theoretical analysis of the phase frequency charcteristics of strong-fed broadband phased array antenna channel. Under the premise of meeting the requirements of the calibration accuracy, the entire frequency band can be obtained by minimizing the test sample data. The data solves the shortcomings of the long point-by-point calibration method of broadband phased array antennas, and can greatly improve the calibration efficiency of strong-fed broadband passive phased array antennas. At the same time, this method is also suitable for channel phase-frequency characteristics with flat or approximately linear, so it has higher application value.
