Matched Field Processing
Abstract
Validation of parabolic equation (PE) full-wavefield modeling in a sloping environment using data from the Summer 1989 Downslope Conversion Experiment. Matched field processing has been quite successful in weakly- dependent environments. Little has been done to validate full-wavefield models in environments which have significant range variation. Examples of these include ridges and continental margin regions. Such bottom features have a significant impact on signal structure, reverberation, and characteristics of ambient noise. The primary thrust of this project was the analysis of SeaBeam bathymetry data in order to obtain spatial spectral characteristics of continental slope roughness. This information has been provided for use in a new reverberation model (not yet completed) to predict the level of backscatter from continental margin regions. The July 1989 Downslope Conversion Experiment studied the physics of downslope propagation which has been proposed as one mechanism by which energy from surface shipping traffic gets coupled into the deep sound channel. As part of that experiment, a SeaBeam bathymetric survey was conducted in the region of the continental slope west of Pt. Conception, CA.
