Demonstrator Performance at the Unexploded Ordnance Advanced Technology Demonstration at Jefferson Proving Ground (Phase 1) and Implications for UXO Clearance.

Abstract

IDA publishes the following documents to report the results ot its work. Reports Reports are the most authoritative and most carefully considered products IDA publishes. They normally embody results of ma|or projects which (a) have a direct bearing on decisions affecting major programs, (b) address Issues of significant concern to the Executive Branch, the Congress and/or the public, or (c) address issues that have significant economic implications. IDA Reports are reviewed by outside panels of experts to ensure their high quality and relevance to the problems studied, and they are released by the President of IDA. Group Reports Group Reports record the findings and results of IDA established working groups and panels composed of senior Individuals addressing ma|or issues which otherwise would be the subiect of an IDA Report. IDA Group Reports are reviewed by the senior individuals responsible for the project and others as selected by IDA to ensure their high quality and relevance to the problems studied, and are released by the President of IDA. Papers Papers also authoritative and carefully considered products of IDA, address studies that are narrower in scope than those covered in Reports. IDA Papers are reviewed to ensure that they meet the high standards expected of refereed papers in professional journals or formal Agency reports. Documents IDA Documents are used for the convenience of the sponsors or the analysts (a) to record substantive work done in quick reaction studies, (b) to record the proceedings of conferences and meetings, (e) to make available preliminary and tentative results of analyses (d) to record data developed in the course of an investigation, or (e) to forward information that is essentially unanalyzed and unevaluated. The review of IDA Documents is suited to their content and intended use. The work reported in this document was conducted under contract DASW01 94 C 0054 for the Department of Defense. The publication of this IDA document does not indicate endorsement by the Department of Defense, nor should the contents be construed as reflecting the official position of that Agency.

Classification of UXO and non-UXO from magnetic anomaly data: a case study on inversion of drone magnetic data from Rømø, Denmark

“…With the inclusion of remanent magnetization, the number of model parameters is further increased as well as the non-uniqueness between the forward models. The spheroid model has been used extensively to model various UXO with similar shapes (Altshuler 1996;Butler et al 1998;. The demagnetization factors for a spheroid can be analytically determined and used to produce the induced dipole moment.…”

“…Utilizing magnetic anomaly data to classify and discriminate between UXO and non-UXO sources have been researched for many years, where spheroidal approximations to the induced magnetization distribution of typical UXO have proven to be an effective application for modelling sources (Altshuler 1996;Butler et al 1998;Billings 2004. However, remanent magnetization is well known to limit the viability of classifying ferromagnetic objects from the magnetic anomaly (Billings & Youmans 2006;Billings 2009;Wigh et al 2020).…”

Research of Ground-Penetrating Radar for Detection of Mines and Unexploded Ordnance: Current Status and Research Strategy

“…• In a mission to identify or classify UXO, where maximum k-space coverage 10 is required for feature extraction. The application of radar to this mission is immature and the likelihood of success is not evident.…”

“…The current HSTAMEDS and VMMD systems (Coleman and EG&G, respectively) could be used for limited clutter-characterization work; however, a purpose-built research-grade instrument to study the greatest accessible k-space is likely to provide far more useful data. 10 k-space is discussed in Appendix A.…”
