摘要

摘要: 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800~1000 km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0.97 km,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。

Abstract: This is the first space debris exploration experiment in China that use Europe Incoherent Scatter(EISCAT) Radar. Based on the principle of ionosphere exploration in EISCAT radar and space debris with high population, the match filter method is used to analyze debris data from Europe incoherent scatter radar expriment on March 25 2010, a 15 hour debris measurement, get 24enents per hours,and by statistical analysis debris population height is got. The result shows that most debris target high locate at between 800 km and 1000 km, which shows good agreement with existent theory model of space debris high population, we run a 15 hour debris measurement, get 24enents per hours, and compared the debris target information at 10:31:05 am March 25, 2010 with theory forecast debris model of National Astronomical Observatories Chinese Academy of Sciences, authenticated that debris target is discard communications satellite of United States, international designator is 1965-065F, errors in high is only 0.97 km, which verify that debris detection method used fixed ionsphere exploration pattern in incoherent scatter radar is feasible.
