中文摘要：

双向式激光测距技术克服传统激光测距系统中距离四次方能量衰减的缺点,可用于行星际高精度激光测距。通过研究双向式激光测距系统中资源和采样率之间的平衡性,可以用适量减少星端资源,增加地面端资源的方法,来达到测距性能最优化。以平衡系统为基础,开展双向式激光测距模拟试验,进而评估上海天文台卫星激光测距系统的行星际测距能力。最后介绍了2005年美国对水星的试验系统MLA。

英文摘要：

Transponder overcomes the large R4 signal loss characteristic of traditional satellite laser ranging,thus it can range to interplanetary distance.Though studying balanced system and sampling rate,one can place as much of the transponder link burden on the Earth station as necessary（within reasonable engineering or economic limits） in order to achieve a ＇balanced＇ and optimized link.Based on the balanced system,we can perform asynchronous transponder simulation experiment.Evaluation the ranging capacity of SHAO′s SLR system is carried out.Finally,we introduce MLA system in interplanetary ranging.
