Keyword激光测距 角反射器 探月卫星
Abstract激光测距技术是一项综合技术,涵盖激光、光电探测、自动控制、空间轨道等多个学科领域,各学科日新月异的发展推动着激光测距技术的进步。激光测距系统经过了三个阶段的发展,衡量每一阶段测距系统产生的标志主要是测距精度。目前,第四阶段预期精度为毫米级,尚处于研制阶段。 本论文引言部分介绍了卫星激光测距技术的发展概况、测距系统的构成、测距网的概况以及在嫦娥工程中,激光测距的意义等;第二、三部分从激光测距理论、角反射器理论出发,探讨了设计角反射器的理论基础及应该注意的基本问题;第四部分对探月卫星激光测距的必要性和可行性进行了分析,提出了单个角反射器及角反射器阵列的设计方案;第五部分介绍了由美国和前苏联放置在月面上的角反射器阵列实例,以此为参考提出了放置在月面上的角反射器阵列的设计方案。 本论文只是该项研究的初步探讨,还有许多未尽的工作,但这些对于推动激光测距理论的发展、促进激光测距技术的进步有重要意义。
Other AbstractLaser Ranging technology is a comprehensive technology, covering a number of areas from laser, photoelectric detection, automatic control to space orbit. The rapid development of these disciplines promotes the progress of Laser Ranging technology. Laser Ranging system experience a three-stage development, of which the location accuracy is the main sign of the ranging system creation. At present, the precision of the fourth phase is expected to be millimeter-level, which is still in the development stage. The introduction of this paper introduces the developments of satellite Laser Ranging technology, the components of ranging system, ranging network and the significance of Laser Ranging in the Chang'e project. Based on the Laser Ranging theory, corner reflectors theory, the second and the third parts discuss the theoretical foundation of the corner reflectors and the basic problem should be pay attention to. The forth part analyses the necessity and feasibility of the lunar exploration satellite Laser Ranging, and presents the design proposal of single corner reflectors and angle reflector array. The fifth part introduces the example that the United States and the former Soviet Union place the corner reflector array on the moon surface. So we present the corner reflector array design placed on the moon surface. This paper is only a preliminary study, there are still many works need to do. However the results are significant for impelling the laser ranging theories, promoting the laser ranging techniques.
