Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
In realistic settings data used as input to any inverse scattering algorithm is bandlimited and corrupted by noise. At present there is no satisfactory way to determine the extent to which reconstructions using imperfect data are degraded due to noise and bandlimiting. In this paper, this problem is considered from the point of view of the sensitivity matrix of the mapping that transforms, via an inverse scattering algorithm outlined below,1 reflection data to information about material profiles of media.
