ShadowDeNet: A Moving Target Shadow Detection Network for Video SAR
Remote Sensing, 2022 Most existing SAR moving target shadow detectors not only tend to generate missed detections because of their limited feature extraction capacity among complex scenes, but also tend to bring about numerous perishing false alarms due to their poor ...

Cooperative Standoff Tracking of Moving Targets Using Modified Lyapunov Vector Field Guidance
Applied Sciences, 2020 Cooperative standoff tracking of moving targets is an important application of fixed-wing unmanned aerial vehicles (UAVs). To cope with the problem of long convergence time and unstable tracking in cooperative target tracking, traditional Lyapunov vector

Valvulogenesis: the moving target [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2007 Valvulogenesis is an extremely complex process by which a fragile gelatinous matrix is populated and remodelled during embryonic development into thin fibrous leaflets capable of maintaining unidirectional flow over a lifetime. This process occurs during exposure to constantly changing haemodynamic forces, with a success rate of approximately 99 ...

Guidance Strategy for UAV Tracking Target Based on Reference Point Guidance Method
Xibei Gongye Daxue Xuebao, 2020 When the target is tracked based on the current traditional reference point guidance method by standoff mode, if the angle between the relative speed of the UAV and the target and the tangential direction of the corresponding point on the circular ...
