Reflectivity of a Layer with Arbitrary Profiles of Density and Sound Velocity
The sea bottom acoustic reflection direct problem has been solved by an upwards integration, from the basement to the upper sediment layer, of an acoustic impedance Riccati equation. The starting data are the water and basement impedance, as well as the arbitrary density and sound velocity profiles of the sediments. The bottom reflection response will be the result of the whole process.
The theoretical model results are compared with those from the experiments. The experimental model refers to a two layer bottom (sand and gravel) made in our laboratory.
