Transport Theory for Propagation and Reverberation

Abstract

Development of computationally efficient modeling methods for shallow water propagation and reverberation that can account for the effects of multiple forward scattering from waveguide boundary roughness and volume heterogeneity such as internal waves. Our objective in FY10 was to improve the generality of our previously developed shallow water propagation model based on transport theory to include range dependent bottom depth. Transport theory, as we have developed it, can account for the effects of multiple forward scattering from boundary roughness. The emphasis of this work is on the mid-frequency range (1-10 kHz) where effects of forward scattering can be important.
