Sparsity-Inducing Super-Resolution Passive Radar Imaging with Illuminators of Opportunity
Remote Sensing, 2016 Multiple illuminators of opportunity (IOs) and a large rotation angle are often required for current passive radar imaging techniques. However, a large rotation angle demands a long observation time, which cannot be implemented for actual passive radar ...

Cooperative Fusion Based Passive Multistatic Radar Detection [PDF]
Sensors, 2021 Passive multistatic radars have gained a lot of interest in recent years as they offer many benefits contrary to conventional radars. Here in this research, our aim is detection of target in a passive multistatic radar system. The system contains a single transmitter and multiple spatially distributed receivers comprised of both the surveillance and ...
