“…Only a few contributions have considered satellite emitters of opportunity for aerial surveillance applications. In [39], the authors exploit the 2.3 GHz downlink of the geostationary XM-Radio satellites to detect aircrafts at short distance. Noticeably, the proposed passive radar system exploiting an X-band GEO-SAR as an illuminator of opportunity represents an innovative solution for air traffic surveillance.…”

Synthetic aperture radar systems operating with satellites in geosynchronous orbits (GEO-SAR) can provide a permanent coverage of wide specific areas of the Earth’s surface. As well as for primary applications in remote sensing areas such as soil moisture and deformation monitoring, the wide availability of the signal emitted by a GEO-SAR on a regional scale makes it an appealing illuminator of opportunity for bistatic radars. Different types of receiving-only devices located on or near the Earth could exploit the same signal source, noticeably already conceived for radar purposes, for applications in the framework of both military and civil surveillance. This paper provides an overview of possible parasitic applications enabled by a GEO-SAR illuminator in different operative scenarios, including aerial, ground and maritime surveillance. For each selected scenario, different receiver configurations are proposed, providing an assessment of the achievable performance with discussions about the expected potentialities and challenges. This research aims at serving as a roadmap for designing parasitic systems relying on GEO-SAR signals, and also aims at extending the net of potential users interested in investing in GEO-SAR missions.

“…As the multi-frame integration is performed on a pixel basis, the highest integration gain could not be reached. (ii) For given bounds of the Doppler rate to test, the sampling rule (6) implies that the number of filters in the bank increases with the number of integrated frames, entailing a direct increase of the computational load.…”

“…However, satellite-based passive radars present some relevant benefits with respect to their terrestrial-based counterparts: Wider accessibility on the global scale, less sensitivity to multipath effects, signals not blocked by mountains, and not reliance on potentially vulnerable infrastructures. Over recent years, the update of the current satellite fleets and the plan of new missions stimulated a rising interest in the development of innovative system concepts and techniques for satellite-based passive radar applications [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

This work discusses methods and experimental results on passive radar detection of moving ships using navigation satellites as transmitters of opportunity. The reported study highlights as the adoption of proper strategies combining target motion compensation and track-before-detect methods to achieve long time integration can be fruitfully exploited in GNSS-based passive radar for the detection of maritime targets. The proposed detection strategy reduces the sensitivity of long-time integration methods to the adopted motion models and can save the computational complexity, making it appealing for real-time implementations. Experimental results obtained in three different scenarios (port operations, navigation in open area, and river shipping) comprising maritime targets belonging to different classes show as this combined approach can be employed with success in several operative scenarios of practical interest for this technology.

“…The limits on useful integration have been explored (e.g., [7,8]), and for a nonfluctuating target the limiting factors are range walk (changing range cells during integration) and velocity walk (changing velocity cells during integration). Velocity walk can be addressed by applying time-frequency analysis to a fixed range cell and identifying the chirp as adopted in [6], leaving range walk as the dominant limiting factor.…”

This paper describes passive radar observations using the ATSC digital television signal as an illuminator. The system has two unique attributes. First, it recovers the reference signal by remodulation of the surveillance channel, a process which permits a compact single-antenna receiver. Second, it is shown that keystone formatting of the cross-ambiguity data mitigates range walk of moving targets and allows meaningful increases to the integration time and sensitivity.
