摘要

摘要: 在中国首次使用欧洲非相干散射雷达三站系统研究空间碎片.以美国OSCAR-3报废业余通信卫星的三站雷达探测散射截面为例,采用欧洲非相干散射雷达三站标准电离层实验模式,分析三站雷达目标散射截面的差异性.比较三站雷达的探测结果表明,Sodanky站雷达散射截面比Tromso站散射截面精度提高5倍;按照中国科学院国家天文台预报理论模型轨道计算,通过理论方向图修正雷达散射截面后,在不知道美国太空监测网所公布的数值时,Tromso站雷达散射截面具有参考价值.计算结果证实三站雷达能提供较为准确的雷达散射截面.

Abstract: This is the first space debris observation experiment using 930MHz Europe Incoherent Scatter (EISCAT) UHF Radar in China. For the purpose of analyzing the discrepancy of tristatic RCS (Radar Cross Section), taking observation satellite named OSCAR-3 as an example, the standard European Incoherent Scatter (EISCAT) ionospheric radar experiment model is used. The results showed that the RCS precision from Sodanky radar is five times higher than that from Tromso radar; according to the forecast debris model of National Astronomical Observatories of Chinese Academy of Sciences and the theoretical antenna pattern, the revised RCS is referential when the U.S. Space Surveillance Network does not provide RCS results. Results of the present work confirm that the tristatic radar could provide higher precision RCS than monostatic.
