AI Technical Summary
Traditional broadband multi-beam antennas cannot achieve rapid on-orbit switching of all beam positions, and cannot meet the high sensitivity and high coverage agility requirements of inter-satellite and satellite-to-ground communication.
The multi-beam phased array antenna control method includes initialization standby mode, normal operation mode, on-orbit correction mode and test mode. It utilizes first-level and second-level beam controllers to achieve broadband correction, narrowband correction or independent correction of the beam. Combined with phase shift control code and attenuation control code, it enables rapid switching of all beam positions of the multi-beam phased array antenna.
It enables rapid on-orbit switching of all beam positions of the multi-beam phased array antenna, meeting the complex functional requirements of the antenna system and improving the sensitivity and beam coverage agility of satellite communication.
