Summary:An adaptive beamforming method for aeronautical communication provided by the invention comprises the following steps: constructing an aeronautical communication system in which a base station is configured with a plurality of antennas, and sectorizing each cell in the system; calculating the beam gain in the sector to obtain an ideal beam pattern of the common channel beam as a reference beam pattern; constructing an optimization model of adaptive beamforming, namely an optimization model of PBAB; and solving the optimization model of the PBAB to obtain a beamforming vector, and completing the adaptive beamforming method for aviation communication. According to the adaptive beamforming method for aeronautical communication provided by the invention, the switching of the serving cell usually occurs when the UE is located at the edge of the cell, so that the PBAB scheme can provide higher beam gain for the UE in a switching state, and the performance of common signal transmission is further improved; the PBAB
