Detecting Moving Target on Ground Based on Its Shadow by Using VideoSAR
Remote Sensing, 2021 Video synthetic aperture radar (VideoSAR) can detect and identify a moving target based on its shadow. A slowly moving target has a shadow with distinct features, but it cannot be detected by state-of-the-art difference-based algorithms because of minor ...

Moving ground target isolation by a UAV using predicted observations [PDF]
53rd IEEE Conference on Decision and Control, 2014 An interesting variant of the cops and robbers pursuit-evasion problem is presented. The motivation for the problem comes from the need to monitor a network of roads leading to a protected area. In this paper, an unmanned aerial vehicle (UAV) is searching for a slower moving ground vehicle on a road network that has been out-fitted with unattended ...

Radar imaging of ground moving targets
Proceedings of the 2001 IEEE Radar Conference (Cat. No.01CH37200), 2002 We analyze the effect of target motion on synthetic aperture radar images and discuss how a multi-aperture radar can detect, focus and relocate moving targets in clutter. AN/APY-6 radar data is used for analyzing the radar imaging of ground moving targets.
