摆动状态下高空平台多波束天线覆盖模型与仿真分析

摘要

Strong wind in the stratosphere will lead to the swing of high altitude platform station(HAPS), which could seriously affect the performance of the communication system. In this paper the swing state of HAPS is described and analyzed, the coverage model of multi-beam antenna on HAPS in the swing state is established, and the expressions of coverage geometry, direction and carrier to interference ratio are derived. The coverage performance of multi-beam antenna on HAPS in the swing state is simulated and analyzed. The results can provide a theoretical reference to the future design of multi-beam cell.%同温层强风导致的高空平台姿态摆动将严重影响通信系统性能.描述并分析平台的摆动状态,建立摆动状态下高空平台多波束天线覆盖模型,推导平台在任意摆动角状态下多波束天线覆盖几何形状、方向性增益以及CIR的表达式.通过仿真分析摆动状态下多波束天线的覆盖性能,为后续多波束小区规划和设计提供理论参考.
