Abstract
The present disclosure discloses an adaptive satellite-aiming method for a low-orbit mobile satellite communication network. The method first receives signals through an array antenna, estimates an offset angle between an array antenna and a satellite beam using a MUSIC-based angle estimation method; then, based on the estimated offset angle, tracks a satellite direction using the adaptive coupling model and achieves tracking and alignment of an antenna direction based on feature parameters extracted during a tracking process; finally, based on the obtained feature parameters, adjusts parameters in the MUSIC-based angle estimation method, and repeats the above steps, to achieve real-time estimation of the offset angle and real-time tracking and alignment of the antenna direction.
