Abstract
Acoustic sources found in the ocean environment are spatially complex and broadband, complicating the analysis of received acoustic data considerably. A model-based approach is developed for a broadband source in a shallow ocean environment characterized by a normal-mode propagation model. Here we develop the “optimal” Bayesian solution to the broadband pressure-field enhancement and modal function extraction problem
