Model Development to Support Analysis of Acoustic Buried Target Data
Abstract
The work reported here makes use of scattering models to understand the high sub-critical-grazing-angle target detection performance initially observed at the SAX99 field test using NSWC PC's synthetic aperture sonar (SAS) system. In this test, cylindrical targets buried as much as 50 cm in a fairly uniform sand bottom with minor roughness on the surface were detected robustly at grazing angles low enough (e.g., below the critical grazing angle) and frequencies high enough that detection would normally be expected to be very difficult. The long-term goal is to identify the mechanism and relevant environmental parameters responsible for detection and use this information to formulate models that reliably predict sonar detection and classification/identification performance against buried mines.
