REAL-TIME PASSIVE ACOUSTIC 3D TRACKING OF DEEP DIVING CETACEAN BY SMALL NON-UNIFORM MOBILE SURFACE ANTENNA
International audience Detecting and localizing the echolocation clicks of sperm whales provides insight into their diving behavior, but existing methods are limited in range, imprecise, or costly. In this work, we demonstrate that we can obtain a high definition 3D track of deep diving cetaceans fr...
