摘要
人卫激光测距是研究地壳形变的现代观测手段之一。每个台站观测后,如何快速准确地剔除噪声,是首先需要解决的问题。为此,本文提出了区域斜率双重限制剔除噪声的方法,此外还描述了估算每圈精度的方法。上述方法已用于武汉人卫激光测距仪的资料处理中,从1989年8月起,武汉站的资料正式发送到NASA人卫激光跟踪系统。由国外对武汉站资料的分析可知,我们的方法准确可靠。
Satellite Laser Ranging(SLR) is one of the modern techniques to investigate the crust movements. For a station when one pass was observed, the first problem met is how to filter the true signals from the hundreds even thousands raw records as fast as possible. The method named deleting noises with interval-rate limitations, which was proposed by the paper, may solve the problem effectively. In addition, the method for estimating the single shot accuracy of a pass was also described in the paper. All the methods described in the paper have been used in Wuhan SLR station. We have sent our data to NASA GLTN since August 1989. The high percentage of using our data by Delft University of Technology, The Netherlands, shows that our method for processing SLR observations is reasonable, effective and reliable.
