Passive radar imaging with GNSS transmitters and a fixed receiver: Latest results

摘要

This paper presents an overview of the latest research results towards the development of a coherent change detector based on passive, bistatic SAR imagery. The proposed system uses navigation satellites as transmitters, while the receiver is fixed on the ground. Potential problems in using such a configuration are briefly described, and a conceptual description of how they were tackled is given. Experimental results are provided where appropriate. Finally, an experimental test-bed designed to confirm the system feasibility is presented.
