Abstract:

The total system concept for the Buried-Mine Minehunting System BURMMS requires the ability to predict the probability that a mine will bury in a given environment. As an expeditious means of providing information upon which to make such a prediction, acoustic techniques hold significant potential. To obtain values for the parameters needed in the mine burial prediction models density, grain size, and shear strength, quantitative relationships between them and acoustically measurable quantities are required. In search of the best quantitative relationship for general BURMMS application, this study explores the very large number of regression equations developed in the literature. Several of these equations are singled out for their potential for predicting values for density and grain size from measured values of sound velocity and reflection coefficient. The report addresses several problems that lead to questions regarding the quality of the prediction in some cases. It recommends a field-measurement and data-analysis program to reduce the uncertainty.
