Synthetic Aperture Sonar Forward Modeling and Inversion.

摘要

Work carried out during this project improved our ability to link SAS image statistics to measurable environmental properties such as seafloor roughness. During the course of this project we: (1) Examined relationships of acoustic scattering properties to SAS means levels and statistics; (2) Developed predictive physics-based forward models of mean levels and statistics relevant to SAS; (3) Developed inversion tools for estimating seafloor properties based on forward models; and (4) Validated forward models and inversion results against at-sea experimental data.
