Space debris cross section observations with 930 MHz radar

This paper proposes that space debris could be observated by using the Europe Incoherent Scatter(EISCAT-UHF)radrar.A special observation model for the space debris was developed to measure the radar cross section(RCS).Recorded raw sample data used the standard EISCAT radar receiver,and the transmission sample signal with match function(MF)analysis is needed from the simulation based on the constant experiment code.The debris RCS diversity using the location of a debris object in radar beam is analyzed.According to the forecast debris model of National Astronomical Observatories Chinese Academy of Sciences and the theoretical antenna pattern,the revised RCS measurements are found to have some extents with the debris value from U S Space Surveillance Network(SSN).The result of the present work confirms that ionosphere observation raw data could provide debris parameter and the revised RCS could provide high precision RCS value.
