Abstract
Using LEO satellite systems to achieve personal mobile communication has many advantages compared to the geosynchronous orbit satellite system. It is a hotspot of research in recent years. However, due to its low orbital height and fast movement speed, LEO system is facing problems such as the user needs to switch beam continually, the effective communication time is too short etc. These phenomena increase the expense of the system. Adaptive beam forming method based on array antenna is an important way to solve those problems. In this paper, a beam forming method of “Staring” is performed. The method proposed can stare at the specific user during the period when the satellite is visible, the computational complexity is reduced by introducing the adaptive algorithm. Thus the satellite can effectively increase the duration for communication, reduce the frequency of beam switching and the system expense.
