Monitoring objects in Earth’s orbit and preventing collisions is becoming an increasingly widespread task. In this regard, several monitoring systems using different type of sensors have been developed over time: Optical, Laser and Radar. In particular, and contrary to optical systems, Radar allows both day and night observation, in every weather condition. The aim of this work is to discuss the feasibility of a DVB-S2 based passive multi-bistatic radar system for the detection and tracking of Resident Space Objects (RSOs) and to consider its advantages, in comparison with active ground-based systems.
