Bottom Backscatterin gMeasured in the Adriatic Sea During the Littoral Warfare Advanced Development 00-3 Experiment
Abstract
The Littoral Warfare Advanced Development (LWAD) 00-3 experiment was conducted in the Adriatic Sea near Bari, Italy in October 2000. Bottom backscattering strength (B SS) in the 0.4 to 5 kHz band was calculated at two shallow water sites using direct path measurements. Bottom backscattering measurements have been performed during seven previous LWAD ex- periments: Focused Technology Experiment 96-2 (FTE 96-2), Focused Technology Experiment 97-2 (FTE 97-2), System Concept Validation 97 (SCV-97), LWAD Experiment 98-2 (LWAD 98-2), LWAD Experiment 98-4 (LWAD 98-4), LWAD Experiment 99-1 (LWAD 99-1) and LWAD Exper- iment 99-3 (LWAD 99-3). The FTE 96-2, SCV-97 and LWAD 98-4 backscattering measurements were made off the Carolina coast and the results appear in 1,2,3. The FTE 97-2, LWAD 98-2 and LWAD 99-1 measurements were made off the western coast of Florida and the results are reported in 4,5,6. The LWAD 99-3 measurements were made off the coast of Oregon and appear in 7. This report presents a summary of the LWAD 00-3 data collection and analysis approach. Following this discussion, BSS results are presented for frequencies from 0.4 and 5 kHz with a comparison to empirical model curves.
