Abstract
Disclosed in the present application are a method and an apparatus for calibrating an antenna. In the method, in a receiving channel calibration process, first a receiving channel beam weight matrix is initially updated by using a receiving calibration signal from a reference beam direction, i.e., performing initial receiving channel calibration, and then, for different beam direction regions, beam weight vectors corresponding to multiple beam directions within particular beam direction regions are updated.
