摘　　要：基于坐标变换方法,建立多波束天线覆盖服务区的数学模型。在考虑对星联系视角限制的情况下,同时引入实时变化的姿轨参数,实现卫星多波束天线覆盖特性的实时动态效果,具有较强的直观性,能够为通信卫星的规划设计提供有效的数据及可视化支持。Based on coordinate transformation method,the mathematic model of covering service area of satellite multi-beam antenna on earth is built up.Considering the restriction on visual angle between satellite and communication terminal,as well as the real-time orbit and attitude parameters,the real-time dynamic simulation effect of satellite multi-beam antenna’s coverage characteristic is achieved.This simulation is so visual that can provide effective data and display to assist in the programming and design of communication satel-lite.
