Challenge Problem and Approach

In this challenge, we applied spectral analysis and acoustic direction of arrival methods to characterize a pair of dolphins’ motion as they swim nearby a transducer array consisting of 3 hydrophones. By utilizing frame-based energy analysis and cross-correlation based time of arrival differences, we were able to localize the dolphins over time and characterize the acoustic and temporal properties of their click emissions. A manuscript detailing our solutions is attached below. See the original problem statement here.
