Abstract

阵列探测技术对回波信号及其微弱的空间碎片激光测距系统具有重要意义,可提高探测成功概率。针对这一崭新的激光测距技术,文中研究了基于阵列探测技术的激光测距数据预处理方法。在常规卫星激光测距数据预处理方法基础上,针对阵列超导探测器特点,结合地靶测量方法和多高斯拟合及互相关分析方法,实现了多通道激光测距数据的通道间的时间偏差修正;利用泊松统计分析、循环拟合滤波等方法,实现了多通道激光测距数据的自动识别、数据拟合等。目前该方法已经成功应用于中国科学院云南天文台4×4阵列激光测距试验平台试验中,并获得良好的效果。

Other Abstract

Array detection technology is of great significance to the laser ranging system for space debris with extremely weak echo signals, because array detection technology can improve the probability of detection success in laser ranging of space targets. Focusing on this new laser ranging technology, the preprocessing method of laser ranging data based on array detection technology was researched in this paper. The research was based on general preprocessing method of satellite laser ranging data. According to the characteristics of the array of Superconducting Nanowire Single Photon Detector (SNSPD), together with the methods of ground target measurement and the methods of multi-peak Gaussian fitting & cross correlation analysis, the time offset correction between channels of the multi-channel laser ranging data was realized. Poisson statistical analysis and cyclic fitting filter were used to realize signals automatic identification and data fitting of multi-channel laser ranging data, etc. At present, this data preprocessing method has been successfully applied in the experiment of 4 × 4 array laser ranging experiment platform of Yunnan Observatory, Chinese Academy of Sciences, this method can correct the time offset between channels of multi-channel laser ranging data, and the application of this data preprocessing method has achieved good results.
