Acoustic Resonance Classification of Swimbladder-Bearing Fish
The long-term goal of this research is to understand and exploit the resonance scattering by swimbladder-bearing fish (typically in the 1-10 kHz frequency region). Exploitation of the resonances can significantly reduce ambiguities in interpreting acoustic scattering in terms of meaningful biologica...

The long-term goal of this research is to understand and exploit the resonance scattering by swimbladder-bearing fish (typically in the 1-10 kHz frequency region).
