ABSTRACT

With the human’s exploration activities of space have become increasingly frequent, the amount of space debris increased gradually, this severely affected the spacecraft launch and normal operation. Detection and identification of space debris has become an important task. GNSS-based microwave remote sensing technology has so many advantages due to a low cost and wide coverage, showing broad application prospects in space exploration. This paper studies used navigation satellites as a transmitter, a receiver located in other space platforms, the target reflecting surface scattering coefficient is extracted by using space debris spins Doppler, then an imaging method based on GNSS-R system is proposed to achieve space debris bistatic narrowband imaging. Its effectiveness is verified through the analysis of simulation results it estimated the size of space debris, It is conducive to further space debris detection and classification.
