摘要
针对卫星同步轨道高度,研制了卫星试验用小型地球模拟器,解决了红外地球敏感器地面模拟试验测试和精度标定问题。介绍了准直式红外地球模拟器总体方案。采用红外光学系统设计与计算技术,设计了锗准直透镜,通过理论分析和光学计算,得出地球光阑、热地球位置和大小与地球张角、锗准直透镜光学参数之间的关系,分析了地球张角偏差和光束平行度偏差对地球模拟器张角的影响,为地球模拟器的研制提供了设计依据。
Aiming at the orbit height 35786Km of planet, this paper advances a minitype earth simulator for satellite experiment, resolving the problems of ground-based experimentation, testing, calibration for the infrared earth sensor. This paper introduces the components and the whole design precept of the miniature collimating infrared earth simulator. Introducing the design of infrared optical system, germanium collimating lens is designed.This paper confirms its optics parameter, finds the relations between earth diaphragm, place and size of hot earth, earth angle by theoretic analysis and optical calculation. It analyzes and calculates earth angle windage and beam parallelism windage and affords design foundation for the research of earth simulator.
