Abstract : Acoustical imaging can potentially provide a buried object classification capability. The image quality is expected to be a function of sediment type, burial depth, and grazing angle. Image degradation is caused by propagation and scattering processes that can be modeled and experimentally measured. Three physical mechanisms were investigated: ghosting, warping, and fogging. Fogging, caused by backscattering from the sediment, is expected to be the limiting factor. A laboratory experiment was conducted to test the findings but the results were inconclusive.
