Efficient, Realistic Physics-Based Modeling for Buried UXO Based on Time-Domain Electromagnetic Scattering Signatures
Abstract
The aim of this effort was to deliver to SERDP a software product suitable for transition to time-domain electromagnetic (TDEM) based sensors currently used for UXO discrimination. The methodology was intended to simultaneously address the requirements of (i) high fi-delity physics-based modelling for realistic target shapes and (ii) vastly accelerated CPU efficiency for forward modeling and inversion, and subsequent discrimination. This aim has essentially been achieved, as described below, through continued development of our highly efficient "mean field" approach, together with the development of an entirely new complementary "early time" approach, to high contrast EM scattering. This Final Report will summarize the substantial advances we have made, describe the nature of the work that still needs to be done to turn our results into a final self-contained product; and finally describe our ongoing and planned future efforts to transition that product to laboratory and field use.
