Coverage model of multi beam antenna from high altitude platform in the swing state

Affected by the stratosphere winds, the swing of high altitude platform station seriously affected the performance of the communication system. This paper described and analyzed the swing state of the platform, established the swing state of high altitude platform multi beam antenna coverage model. The expression of coverage geometry, received power and carrier interference ratio was derived. In the swing state, the performance of multi beam antenna is simulated and analyzed, which provides a theoretical reference for the future design of multi beam cell.
