Abstract:

The ISR (Incoherent Scatter Radar) raw sampling data (time duration about 7 hours) is processed by Matching Filter (MF) method and totally 394 space debris are detected. Parameters including the height, radial velocity, Radar Cross-Section (RCS), effective diameter and radial velocity etc. are estimated, and statistical analysis about these parameters is made. The results show that the mean flux per hour through the radar beam is 60; the signal to noise ratio of space debris echo is above 10, which shows that the space debris is a strong target for ISR; the orbital height mainly is in two zones (600~1100km and 1400~1600km); the RCS is about 10-5~10-2m2 and the effective diameter is about 3~10cm; the radial velocity is about -1.5~1.5km·s-1; the radial acceleration is about 20~90m·s-2. These results show the good perspective for ISR in the monitoring and forecasting of space debris.
