Passive radar downrange imaging with multiple transmitters and one receiver
IET Radar, Sonar & Navigation, 2022 Passive radar systems use illuminators of opportunity to illuminate targets instead of dedicated radar transmitters. The signals of opportunity have lower bandwidth than dedicated active radar systems, leading to poor downrange resolution.

Performance considerations for positioning with signals of opportunity
2016 International Conference on Localization and GNSS (ICL-GNSS), 2016 This paper presents a study on the benefit of observing several signals of opportunity for positioning purposes. Several static emitters are placed over a defined area where an user is moving and acquiring measurements to each of these emitters. The simulation considers that the user is capable of acquiring time of arrival measurements from several ...
