Abstract
Space-borne passive radar (PR) exploits non-cooperative signals of satellite constellations, specifically Low-Earth-Orbit (LEO) communication satellites. It offers advantages such as low intercept probability and reduced costs. However, utilizing LEO signals presents challenges as multiple similar signals from different satellites can interfere without identification. This paper proposes a method for LEO communication signal separation and target detection leveraging synchronization signal blocks (SSB) for discrimination and identification, generating a reference signal for subsequent processing to transfer target information to the range-Doppler domain. The final integration result enables the detection and localization of the target. The effectiveness of the proposed method is validated through simulated experimental results.
