Abstract
Provided are a phase difference measurement method and system for an antenna array, and a phase compensation method and system for an antenna array. The antenna array includes at least two array elements. The phase difference measurement method includes: measurement is performed to obtain a three-dimensional space far-field phase data set of each array element in an antenna array; a three-dimensional solid angle space is determined, and three-dimensional space far-field phase data of each array element is acquired from the three-dimensional space far-field phase data set, wherein the three-dimensional space far-field phase data of each array element corresponds to the three-dimensional solid angle space, of each array element in the antenna array; and with a three-dimensional space far-field phase data of a first array element in the antenna array as a reference, a phase difference between other array element and the first array element is obtained.
