Environmental Data from UUV Systems and Purple Star.

Abstract

This is a progress report for the first year of work on bottom classification using tactical sensors. Data from a TVSS experiment in 1994, at deep and shallow sites, were provided by CSS and distributed by NRL/SSC. The data were processed and analyzed to provide calibration in a self-consistent manner and then to compute the magnitude of the normal incidence bottom reflection coefficient, which was then used to estimate bottom type. Difficulties due to clipping of the signal were detected and partially overcome.
