这是我国首次用欧洲非相干散射雷达探测空间碎片的实验。根据非相干散射探测原理和空间碎片高度分布的规律,采用匹配滤波方法处理了2010年3月25日15小时实验数据,每小时平均24个碎片,用统计方法分析了碎片高度分布。结果表明:大部分碎片分布在高度为800～1000km之间,与碎片高度分布理论一致,与中国科学院国家天文台空间碎片预测理论模型比对,比较2010年3月25日10点31分05秒目标信息,高度误差仅为0.97km,确认为碎片国际标识为1965-016F的美国报废业余通信卫星,证实了非相干散射雷达设备直接探测碎片的可行性。 This is the first time that China has used the European incoherent scatter radar to detect space debris. According to the principle of incoherent scattering detection and the spatial distribution of debris, the matched filter method was used to process 15 hours of March 25, 2010 experimental data, with an average of 24 fragments per hour. The distribution of debris height was analyzed by statistical method. The results show that most of the debris are located at a height of 800-1000 km, which is consistent with the theory of debris height distribution and compared with the theoretical model of the space debris prediction of the National Astronomical Observatories of the Chinese Academy of Sciences. Compared with the target of 10:31:05 on March 25, 2010 Information, a high degree of error of only 0.97km, identified as US scrapped amateur communications satellites identified by the International Division of Fragmentation International 1965-016F, confirms the feasibility of direct detection of debris by incoherent scatter radar equipment.
