摘要
Abstract
The basic concept of the antenna phase center is described simply. The measuring principle and the procedure of feed horn phase pattern are introduced by using vector network analyzer. The simple method of determination phase center is discussed through adequate shift to the axis of horn by using measured phase patterns. A simple method of fast determining phase center is given by calculating actual adjusting size of feed phase center location by using the far field mathematics equation, and an measuring example of C band horn is given. The measurement results validate the correctness of theory analysis. At last, the measurement errors of phase center are analyzed, and it＇ s mean square error is less than or equal to ±1.69mm.关键词
