摘　　要：本文通过分析天体位置,综合考虑反射面上相邻节点距离变幅度、促动器径向伸缩范围,建立电磁波反射面板调节的线性规划模型,并进行优化设计。首先介绍发射面板调节的工作原理,并论证调整反射面板使之成为可聚焦电磁波信号至焦点的理想抛物面的可行性。利用坐标旋转的方法,针对天体的位置调整反射面板,使接收器尽可能收到多的电磁波信号。利用促动器拉伸主索节点以调整反射面板,借助于球坐标系和坐标旋转的方法得到理想的抛物面,有效的控制整个天体信号反射系统。In this paper,by analyzing the position of celestial bodies,considering the variable range of the distance between adjacent nodes on the reflecting surface and the radial expansion range of the actuator,a linear programming model for adjusting the electromagnetic wave reflecting panel is established and optimized.Firstly,the working principle of adjusting the emission panel is introduced,and the feasibility of adjusting the reflection panel to become an ideal paraboloid that can focus the electromagnetic wave signal to the focus is demonstrated.By using the coordinate rotation method,the reflecting panel is adjusted according to the position of the celestial body,so that the receiver can receive as many electromagnetic wave signals as possible.In this system,the main cable node is stretched by the actuator to adjust the reflecting panel,and the ideal paraboloid is obtained by means of spherical coordinate system and coordinate rotation,which effectively controls the whole celestial signal reflecting system.
