摘要
提出了基于漫反射激光测距数据估算火箭残骸质心位置和翻滚姿态的方法。分析了火箭残骸的翻滚运动, 建立了漫反射激光测距仿真模型, 详细介绍了估算火箭残骸翻滚轴指向和翻滚周期的理论和仿真方法。采用快速Lomb-Scargle算法对德国Wettzell站测得的Soyuz火箭末级残骸的实测数据进行了分析, 通过比较仿真和实测数据的统计直方图, 推算了火箭残骸的长度及质心位置, 估算得到其观测周期为11.4 s, 赤经为203°, 赤纬为23°。
Abstract
A method is proposed to estimate the mass centre position and tumbling motion of rocket body using diffuse reflection laser ranging data. The tumbling motion of rocket body is analysed and the diffuse reflection laser ranging model is built. The theoretical and simulation methods are presented to estimate the tumbling axis orientation and tumbling period of rocket body. The laser ranging data of last stage Soyuz rocket body measured at Wettzell station are processed with the fast Lomb-Scargle algorithm. The length and mass centre position of rocket body are deduced by comparing the histograms of simulated and measured data. The tumbling period is estimated to be 11.4 s, the right ascension is 203°, and the declination is 23°.
