Satellite-borne phased-array antenna beam control and dual-redundancy beam control system and method

The invention provides a satellite-borne phased-array antenna beam control system and method, and a processor module is in communication connection with a satellite service computer, and is used for receiving satellite platform orbit, attitude and ground station position information, carrying out beam pointing angle calculation, generating beam pointing azimuth angle information and beam pointing pitch angle information, and transmitting the beam pointing azimuth angle information and the beam pointing pitch angle information to the satellite service computer. The beam pointing azimuth angle information and the beam pointing pitch angle information are converted to obtain an amplitude control code word and a phase control code word of target beam pointing, and the amplitude control code word and the phase control code word are sent to the FPGA module; and the FPGA module sends the amplitude control code word and the phase control code word to a radio frequency module of the phased-array antenna according to t
