Abstract
The necessary actions connected with interpretations of examining of physical properties of sea bottom structure is developing of proper procedure of modeling of the layered structure. The implementation of the acoustic waves for the determination of seabed stratification requires a precise diagnosis of the topic from both the theoretical and practical side. Little differences between the parameters of sediments, as well as irregular distance between layers make the interpretation of the images of cross sections uneasy. The paper presents the model of stratified structure of seabed in the form: of a liquid on which falls the perpendicular elastic wave. Since the description of the seabed is made on the basis of reflected impulse shape, which provides the information about the structure and material properties such as density and speed of wave propagation, the important role among other things has the spatial resolution, because the pulse length determines the possibility of distinguishing between the layers. These aspects require very careful analysis of the form of reflected signals.
