UAV Micro-Doppler Signature Analysis Using DVB-S Based Passive Radar
Radar, 2020Drones and unmanned aerial vehicles (UAVs) are increasingly popular, thus posing danger and threats to infrastructures and public safety. A technology for drone detection and classification would therefore significantly increase the level of security. In

Passive (cooperative) hologram radar
Proceedings of the IEEE, 1970The extension of stationary-coherent radar to a purely passive configuration and to a cooperative active configuration is described. A possible use in airport surveillance of aircraft is noted.

Passive coherent location radar demonstration
Proceedings of the Thirty-Fourth Southeastern Symposium on System Theory (Cat. No.02EX540), 2003This paper describes a passive coherent location (PCL) radar system developed by Dynetics, Inc. This system uses commercial FM broadcast signals for the radar waveform. This paper presents a technical description of the system and performance data.

A Passive radar system is able to operate fully independent of illuminators of opportunity. In most cases these illuminator sources are traditional telecommunication or broadcast signals. During the design of a passive radar we are trying to exploit the opportunities of an already existing system, thus we need to face such problems that could be simply

Passive radar is one of the most rapidly developing fields in the radar technology in recent years. The ground-based passive radar technology is now entering a stage of maturity. In the past, in a case of active radars, the technology developed for ground-based sensing was adapted for airborne platforms.

Passive radar sensor cluster operation
2014 15th International Radar Symposium (IRS), 2014Passive Radar systems use the target illumination by third-party transmitters, e.g. FM radio or terrestrial TV broadcast stations, for target detection and localisation. In 2010 Airbus Defence & Space initiated the development of a mobile multiband Passive Radar demonstrator, processing FM (analogue radio), DAB (Digital Audio Broadcast) and DVB-T ...

Non-Coherent DVB-S Passive Radar Demonstrator
2020 21st International Radar Symposium (IRS), 2020In recent years passive radar systems research has been increasingly focused on the use of satellite opportunity signals, and DVB-S signals in particular, since these offer virtually global coverage. Several papers have been published recently proving the effectiveness of very simple demonstrators based on COTS.
