Title:
METHOD, DEVICE AND SYSTEM FOR ANTENNA ARRAY CALIBRATION
Document Type and Number:
WIPO Patent Application WO/2016/202258
Kind Code:
A1
Abstract:
Disclosed are a method, device and system for antenna array calibration. The method at least comprises one of the following steps: acquiring a first signal and a second signal, and obtaining a relative emission amplitude-phase coefficient between a second array element and a third array element by calculation according to the first signal and the second signal, so that the amplitude-phase characteristic of a first emission channel of the second array element is consistent with that of a second emission channel of the third array element; acquiring a third signal and a fourth signal, obtaining a relative reception amplitude-phase coefficient between the second array element and the third array element by calculation according to the third signal and the fourth signal, so that the amplitude-phase characteristic of a first reception channel of the second array element is consistent with that of a second reception channel of the third array element, the third signal being a signal sent by a first array element which is received by the second array element via the first reception channel, and the fourth signal being a signal sent by the first array element which is received by the third array element via the second reception channel.
