摘要
旋转抛物面型多反射镜拼接结构的天线在空间激光多点间激光通信中有着重要的应用。选取不同的旋转抛物面基底面型，系统有不同的通信范围。针对作为基底的旋转抛物面面型进行研究，讨论了不同抛物线系数p 与通信范围θ 之间的关系，分析了不同有效口径下的通信范围，及其合理性。结果表明，在合理的取值范围下，抛物线系数p =28时，最大通信角度可以达到118.7377°，但由于后续拼接反射镜的因素限制，得出合理选择抛物线系数p =50时的面型，而此时通信范围为109.8084°。
Abstract
Rotating paraboloid mirror mosaic structure antenna has important applications in the multi- point space laser communication. Different rotating paraboloid base surfaces result in different communication ranges.The relationship between the parabola coefficient p and communication range θ with different effective apertures is discussed rationally. The results show that the maximum communication angle can achieve 118.7377° ，where the parabola coefficient p is 28 in the reasonable range. However, because of restrictions coming from the following system, the surface need to be a reasonable choice that the parabola coefficient p is 50, and the maximum communication angle is 109.8084°.
