The application discloses a high-power microwave antenna establishing method, and belongs to the technical field of antennas. The method comprises the following steps: determining the total radiation aperture of the antenna according to the size and gain requirement of the microwave antenna of a system, and estimating the aperture and quantity of the required transmitting antenna by considering the beam synthesis efficiency; and selecting a proper rotating table according to the aperture and quantity of the transmitting antenna. Since the antennas are installed on the same rotating table, the consistency between the antennas can be ensured through a tooling, so that all the antennas can be simultaneously aimed at a target or a certain direction by rotating the rotating table, the signal transmitting distances of the antennas to the target are the same, and the effective radiation power in a certain direction can be maximized by only ensuring that the amplitude, phase and time delay of the front-end link of the transmitting antenna are the same. Since the antennas are on the same rotating table, the driving systems of the antennas are the same, and the influence of the time delay between different driving systems is eliminated.
