天线相位中心的推算及标定

Calculation and Measurement of Antenna Phase Center

介绍天线相位中心的基本概念,推导天线相位中心的求解公式,利用修正相位方向图计算出天线的相位中心,最后给出暗室中天线相位中心的标定方法,同时编写程序实现快速计算。

The concept of antenna phase center is introduced at the beginning,and then the calculation formula is deduced to find out the phase center.The estimated phase center is used to modify the phase pattern.After searching in some range,the point which makes the undulation of the modified phase pattern reach the minimum is the final phase center.Finally,the measurement method of phase center in the chamber is discussed and the program is given to search the phase center quickly.
