Abstract :
This Oceans 93 paper describes full nonlinear inversion that gives quantitative reconstructions of submerged and/or buried objects with the aid of a layered Greens function. The computational speed is preserved by use of Fast Fourier Transforms and stabilized biconjugate gradients, for both the homogeneous background and layered background case
