Coordinated standoff tracking of moving target groups using multiple UAVs [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2015
This paper presents a methodology for coordinated standoff tracking of moving target groups using multiple unmanned aerial vehicles (UAVs). The vector field guidance approach for a single UAV is first applied to track a group of targets by defining a ...

Coordinated standoff tracking using path shaping for multiple UAVs [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2014
A coordinated standoff target tracking strategy using path shaping for multiple unmanned aerial vehicles (UAVs) is presented. In performing a tracking mission of a ground target of interest, UAVs are to approach a target and to keep a standoff distance ...

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

A Two-Layer Framework for Cooperative Standoff Tracking of a Ground Moving Target Using Dual UAVs

Drones
Standoff tracking of a ground-moving target with a single fixed-wing unmanned aerial vehicle (UAV) is vulnerable to occlusions around the target, such as buildings and terrain, which can obstruct the line of sight (LOS) between the UAV and the target ...
