Cognitive Radars: A Reality? [PDF]
arXiv, 2018 This paper describes some key ideas and applications of cognitive radars, highlighting the limits and the path forward. Cognitive radars are systems based on the perception-action cycle of cognition that sense the environment, learn from it relevant information about the target and the background, then adapt the radar sensor to optimally satisfy the ...

MetaRadar: Multi-target Detection for Reconfigurable Intelligent Surface Aided Radar Systems [PDF]
arXiv, 2022 As a widely used localization and sensing technique, radars will play an important role in future wireless networks. However, the wireless channels between the radar and the targets are passively adopted by traditional radars, which limits the performance of target detection.

On-the-Fly Interrogation of Mobile Passive Sensors from the Fusion of Optical and Radar Data [PDF]
2024 54th European Microwave Conference (EuMC), European Microwave
Conference (EuMC), Sep 2024, Paris, France. pp.1118-1121In this paper a new method based on the fusion of optical and radar data is proposed to detect and remotely interrogate mobile and passive sensors. The sensors are detected in real time by using an optical camera, while their remote reading is carried out on the fly using a Frequency-Modulated Continuous-Wave radar.

Investigating Nearby Exoplanets via Interstellar Radar [PDF]
, 2013 Interstellar radar is a potential intermediate step between passive observation of exoplanets and interstellar exploratory missions. Compared to passive observation, it has the traditional advantages of radar astronomy. It can measure surface characteristics, determine spin rates and axes, provide extremely accurate ranges, construct maps of planets ...
