Abstract

This paper discusses an aspect of spatially varying dissipative (extinction) and reflective (backscattering) losses that ultimately may allow a relatively quick appraisal of measured data quality, using a new figure of merit q(x), after some limited preprocessing. In order to do this, the paper presents the exact analytical, closed-form, finite solution for the inversion of the classical first-order nonlinear Riccati differential equation (RDE) which relates the reflection coefficient (R) and its derivative (dR/dx) to the otherwise arbitrary profiles of the media parameters [(epsilon) ₁(X) equals (epsilon) ₁(X) - j(epsilon) ₂(X)] in the coefficients of the RDE. This synthesis assumes a deterministic medium which can be accurately represented by the usual media parameters.
