Instantaneous Passive and Active Detection, Localization and Monitoring of Marine Mammals of Long Ranges with High Resolution Towed Array Measurements
The PIs propose to use existing data collected during the 2006 ocean acoustic waveguide remote sensing (OAWRS) Experiment in the Gulf of Maine to develop passive and active methods for tracking marine mammals in near-real-time. The goals of the proposal include development of signal processing techniques for near-real-time localization and ranging of marine mammal vocalizations using a high-resolution array, including using the array invariant method for ranging, adaptive non-linear matched filter processing for improved SNR of signals, and modeling to estimate the performance of the developed algorithms in variable levels of noise. Additional effort will be used to estimate the low frequency target strengths of localized marine mammals from the passive acoustic analysis phase in the study.
