空间交会对接微波雷达测量系统地面校准技术研究

The Research on Topocentric Calibration of RVD Radar Measurement System

介绍一种空间对接雷达测量系统地面校准方法。使用三坐标测量机准确标定立方镜和雷达天线之间的关系,将雷达天线和应答机天线分别固定在两空间舱上,在实验现场使用经纬仪测量系统测试。在测试过程中使用空间坐标转换方法,对位置关系中的姿态角进行标校,验证雷达测量系统的测量准确度,确保空间对接舱在太空中对接成功。

A topocentric test method of the rendezvous and docking （RVD） radar Measurement System is introduced. The CMM is used to accurately measure the relationship between cube mirror and radar antenna. The radar antenna and responder beacon are fixed respectively on the two spatial cabins and the radar measurement system is calibrated by electronic theodolite measurement system. The meth- od of space coordinate transformation is used to calibrate the attitude angle of position relation during the measuring process. It can validate the measuring accuracy of the radar measurement system to make sure the space docking successfully.
