Use of an unmanned aerial‐aquatic vehicle for acoustic sensing in freshwater ecosystems

Remote Sensing in Ecology and Conservation, Volume 10, Issue 3, Page 343-359, June 2024.
In this article, we integrate water surface and underwater acoustic monitoring equipment onto a prototype unmanned aerial‐aquatic vehicle (UAAV) capable of sailing and flight (SailMAV), to demonstrate how robotics can facilitate acoustic sensing in freshwater ecosystems. Results show higher species richness and call abundance from UAAV surveys and high

Deep learning‐based time delay estimation for motion compensation in synthetic aperture sonars

IET Radar, Sonar &Navigation, Volume 18, Issue 5, Page 740-753, May 2024.
In this study, a subband processing and lightweight neural network‐based time delay estimation method is introduced to SAS motion estimation and compensation. The results of time delay estimation and motion compensation demonstrate that the proposed method has better performance than the reference method.
