Title:
METHOD AND SYSTEM FOR MEASURING PHASE CONGRUENCY COMPENSATION VALUE OF ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2022/193402
Kind Code:
A1
Abstract:
The present application relates to a method and system for measuring a phase congruency compensation value of an array antenna. The method comprises: positioning an array antenna to be measured to a desired measurement position, the desired measurement position comprising a first measurement position, and the first measurement position indicating a position where a first radiation surface of said array antenna is parallel to a second radiation surface of a source antenna and a first physical center of the first radiation surface is aligned with a second physical center of the second radiation surface; and on the basis of a test signal received by each antenna array element in said array antenna from the source antenna, determining a phase congruency compensation value of each antenna array element at the desired measurement position.
