Resource management for wireless networks of bearings-only sensors
… management or sensor allocation when we use bearings-only measurements to track targets in an unattended ground sensor (UGS) network. Intelligent resource management is necessary because each UGS sensor node has limited power and it is desirable that estimation performance not degrade very …

Bearings-only tracking automation for a single unmanned underwater vehicle
… In particular, UUVs have the ability to perform bearings-only tracking in shallow areas near shorelines. This thesis presents a guidance algorithm for this particular mission. This thesis first presents a Modified Polar Extended Kalman Filter for the estimation problem. Bearings-only tracking is …

Persistent vision-based search and track using multiple UAVs
… the video data is noisy. Next, a cooperative, bearings-only target estimation algorithm is presented. The algorithm is shown to provide better estimates of a target's position and velocity in three dimensions than could be achieved by a single vehicle, while being computationally efficient and …

Trajectory optimization for target localization using small unmanned aerial vehicles
… to determine the target's location. This 3-D bearings-only estimation problem is nonlinear and traditional filtering methods produce biased and uncertain estimates, occasionally leading to filter instabilities. Careful selection of the measurement locations greatly enhances filter performance, …
