Abstract
An accurate model of high-frequency reflection loss at the ocean bottom is critical to understanding shallow water sound propagation and the detection and classification of buried objects such as mines. The value of the observed reflection coefficient can be perturbed by such effects as scattering from a rough interface and dispersion in the ocean sediment. To obtain ground truth measurements for model development and verification, reflection coefficients from a rough water/sediment interface were measured as part of the experiments for validation of acoustic modeling techniques (EVA) sea test on the north shore of Isola dElba, Italy. Data at grazing angles from 10–80 deg and frequencies from 5–50 kHz were obtained. Experimental effects such as transducer response and spherical wave effects were quantified. The data will be analyzed to determine the influence of dispersion and scattering effects. [Work supported by ONR, Ocean Acoustics.]
