Temporal modeling of high frequency (30-100 kHz) acoustic seafloor backscatter: shallow water results
A temporal model of high frequency seafloor acoustic backscatter is presented and compared to recorded echoes from terrigenous sediments. Using acoustic properties correlated with mean grain size, the echo shapes and amplitudes of the model are compared to data collected in San Diego Harbor with fully calibrated 33 kHz and 93 lcXz narrow beam piston transducers. While there is considerable variation for small horizontal translations of the transducer, the mean echo envelopes compare well with the shapes and amplitudes predicted by model simulations.
