Integrated Sensing and Communication for Large Networks using Joint Detection and a Dynamic Transmission Strategy [PDF]
arXiv, 2022 A large network employing integrated sensing and communication (ISAC) where a single transmit signal by the base station (BS) serves both the radar and communication modes is studied. We consider bistatic detection at a passive radar and monostatic detection at the transmitting BS.

Deep Learning for Waveform Estimation and Imaging in Passive Radar [PDF]
, 2018 We consider a bistatic configuration with a stationary transmitter transmitting unknown waveforms of opportunity and a moving receiver, and present a Deep Learning (DL) framework for passive synthetic aperture radar (SAR) imaging. Existing passive radar methods require two or more antennas which are either spatially separated or colocated with ...

Target Coordinates Estimation by Passive Radar with a Single non-Cooperative Transmitter and a Single Receiver [PDF]
Journal of Communications Software and Systems, 2020 Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following ...

Mode Selection and Target Classification in Cognitive Radar Networks [PDF]
arXiv, 2023 Cognitive Radar Networks were proposed by Simon Haykin in 2006 to address problems with large legacy radar implementations - primarily, single-point vulnerabilities and lack of adaptability. This work proposes to leverage the adaptability of cognitive radar networks to trade between active radar observation, which uses high power and risks interception,

Coded Aperture Radar Imaging Using Reconfigurable Intelligent Surfaces [PDF]
arXiv, 2023 In this paper, we focus on radar imaging using active sensing with a single transceiver and reconfigurable intelligent surface (RIS). RISs are arrays with tunable passive phase shifter elements that can modify the propagation channel. The RIS reflects each transmit pulse with a different phase profile.

Feasibility Study of Using 5G Signals for Illumination Purposes in Passive Radar
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. Passive radars perform target detection based on reflected signals emitted by third-party transmitters. The absence of its own transmitter determines the main advantages of passive radars compared to conventional active radars: lower cost ...
