An algorithm for forward and inverse scattering in time domain

This paper presents an alternative numerical scheme for a class of forward and inverse scattering problems based on invariant imbedding method [Corones et al., J. Acoust. Soc. Am. 74, 1535–1541 (1983)]. The algorithm presented in this paper is decoupled more than the previous implementations and hence, readily amenable to parallel processing. It is also shown that the effect of this decoupling on error can be expressed in terms of the estimated reflection coefficients, facilitating the decision to accept or reject any computed parameter.
