【摘要】：激光反射器作为一种被动无源光学合作目标,是人造卫星激光测距系统中的重要组成部分。对于运行在低轨卫星中的激光反射器,既要在较大的激光入射角范围提供服务,又要将角反射器阵列结构所引入的综合测距误差控制在一定范围内,以保证高精度的激光测距,因此绝大多数采用半球形阵列结构。文中以我国海洋二号卫星激光反射器为例,对半球形激光反射器的远场衍射分布、相对有效反射面积分布、距离更正误差分布和激光测距综合精度等核心技术参数进行理论分析。并以国内流动式卫星激光测距系统TROS1000对海洋二号卫星激光反射器进行追踪和激光测距实验,测量结果表明,激光测距内符合精度为1.1 cm,理论分析与实测结果相符。标志着海洋二号卫星激光反射器性能优良,这对以后激光卫星反射器的设计具有指导意义。
[Abstract]:Laser reflector as a passive optical cooperative target is an important part of satellite laser ranging system. The laser reflector runs in low earth orbit satellites in the both to provide services in large laser incident angle range, and error ranging retroreflector array structure of the control in a certain range in order to ensure high precision, laser ranging, so most of the hemispherical array structure. Based on China's marine two satellite laser reflector as an example, the far field diffraction distribution on spherical laser reflector, the effective reflection area distribution, distance correction error distribution and laser ranging precision integrated core technology parameter theory based on the system analysis. The domestic mobile satellite laser ranging TROS1000 tracking and laser ranging experiment on marine two satellite laser reflector, the measurement results table The accuracy of the laser ranging is 1.1 cm. The theoretical analysis is consistent with the measured results. It indicates that the reflector of Ocean two satellite has excellent performance, which is of guiding significance for the design of the laser satellite reflector.
