Inferring activity patterns of aquatic animals from single‐receiver acoustic telemetry setups
Methods in Ecology and Evolution, Volume 16, Issue 12, Page 2931-2944, December 2025.Abstract Acoustic telemetry has become an essential tool for studying activity patterns of animals in aquatic environments. Activity is typically recorded using transmitters with integrated sensors or dense receiver arrays for positional tracking. While effective, these approaches are financially and logistically expensive due to the need for advanced ...

Joint TDOA and AOA location algorithm
Journal of Systems Engineering and Electronics, 2013 For the joint time difference of arrival (TDOA) and angle of arrival (AOA) location scene, two methods are proposed based on the rectangular coordinates and the polar coordinates, respectively. The problem is solved perfectly by calculating the target position with the joint TDOA and AOA location.
