Iterafive Nonlinear Inversion Methods for Tomographic Problems

Abstract

The application of nonlinear iterafive algorithms to two-dimensional tomographic reconstructions is discttszed and a number of numerical examples are given, using as an illustrative basis reconstruction of the spatial distribution of liquid water in clouds from measurements of microwave attenuation. (The method, however, is not restricted to that specific problem and appears to be especially suitable for inversions involving a large number of unknowns.)
