Multi-beam calibration method suitable for high-throughput satellite receiving and transmitting separated antenna

The invention discloses a multi-beam calibration method suitable for a high-throughput satellite receiving and transmitting separated antenna. The multi-beam calibration method comprises the following steps: S1, carrying out site selection design on a calibration station; s2, feed source design of a receiving antenna and a transmitting antenna; and S3, under the cooperative participation of the two calibration stations, receiving and transmitting two pairs of antennas are calibrated in a time-sharing manner. According to the invention, an uplink calibration scheme is provided for two pairs of antennas separated for receiving and transmitting of a high-throughput satellite, and the two pairs of antennas can share a calibration station through time-sharing calibration of the two pairs of antennas, so that the construction cost of the calibration station is saved; according to the uplink calibration scheme of the transmitting antenna, the time delay of ground processing and satellite-ground propagation in the do
