This paper describes recent results from an ongoing measurement and modeling effort investigating shallow grazing angle acoustic detection of targets buried under a rippled bottom. The measurements are being performed in a 13.7-m deep, 110-m long, 80-m wide test-pool with a 1.5-m layer of sand on the bottom. The rippled bottom is formed by scraping the sand with a machined rake. A parametric sonar...
This paper describes recent results from an ongoing modeling and measurement effort investigating shallow grazing angle acoustic detection of targets buried in sand. The measurements were performed in a 13.7-m deep, 110-m long, 80-m wide test-pool with a 1.5-m layer of sand on the bottom. A silicone-oil-filled target sphere was buried under a rippled surface with contours formed by scraping the sand...
