Detecting sound in the Arctic
An aerial drone flies over a field in Fairbanks, Alaska. A team of researchers from the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory are developing new methods for detecting, localizing and identifying aerial drones in order to determine the direction of sound, the way it travels through the atmosphere, and the way it interacts with terrain in hopes of finding new methods for extracting information from sound signals.
