摘要: Shear wave velocities in the sediment can be inverted by using dispersion curves of interface wave. It done use an algorithm based on singular value decomposition (SVD). This method only invert shear and requires knowledge thicknesses densities layers. paper presents a new for inversion geoacoustic parameters that we have coined "mixin inversion". Mixin combines SVD global search genetic (GA). The GA searches depths doing velocity with each its parameter values. applied cases where depths, sediments are unknown. advantage is it faster than pure since space much smaller fails because necessary information about not known.
