Wide-area persistent synthetic aperture radar (SAR) video offers the ability to track ground-moving targets via changes between video frames. A shortcoming is the difficulty in maintaining track when a Doppler shift places moving target returns colocated with strong clutter. We propose to augment...
A finite-time control scheme for autonomous body-fixed hovering of a rigid spacecraft over a tumbling asteroid is presented. The relative configuration between the spacecraft and asteroid is described in terms of exponential coordinates on the Lie group SE(3), which is the configuration space for...
We address the problem of hover flight and translational velocity regulation of a quad-rotorcraft unmanned aerial vehicle (UAV) with the main objective of allowing the vehicle to navigate autonomously. This paper complements and improves previous researches considering multiple-camera systems and...
