Bottom scattering is a complex physical phenomenon. Movement of the vessel has an effect on the convolution of the transducer beam pattern function and the oblique back reflection function of the bottom. If we extract from the first and second bottom echo components of an echo signal related to the hardness and roughness of the seabed, then the clusters boundaries (rectangular fields) representing different bottom categories can be established in x/y coordinates.  2, fiche 1, Anglais, - bottom%20scattering
