摘　　要：本文根据立体空间中点、线、面之间的几何关系,对卫星天线点波束覆盖地球表面区域的算法进行了研究,给出其解析方法及其相应的计算机软件编程算法。This paper introduces the algorithm for coverage scope of satellite point beams. First we introduce the analytic method, then give the algorithm for coding. According to the geometric relationship of points, lines and planes in space, corresponding algebra eaquations are deduced, and the coordinates of boundary points of coverage scope are obtained by assuming some initial value conditions.
