Abstract
The research covered in this contract is directed to improving the effectiveness of EMI mine detectors of the kinds typically used in humanitarian demining. More specifically, it focuses on the effect of "difficult" (ferromagnetic mineral containing) soils on performance of the detectors. It began with a period of exploratory studies and goal identification; with the objectives then being specified more clearly. Originally, the main objective was a computer modelling code which could also model the problematic soils. The chief variation from that plan was inclusion of an instrument development and a sample measurement phase. Originally, the program was intended to finish by 31 March 2006, but because of the success of the instrument phase, it was extended an additional year to allow for construction of two additional instruments for delivery to the Scientific Authority, and also to allow results of earlier phases to be incorporated into the modelling code. The overall purpose of the project is to facilitate the design of electromagnetic induction (EMI) mine detectors for humanitarian demining purposes. The specific aim is to help designers optimize the ability of these devices to detect low metal, anti-personnel mines in what are called "difficult" soils (considered here mainly to be those soils that contain appreciable quantities of electromagnetically lossy ferromagnetic minerals). Present day EMI mine detectors are already very refined devices. If one is to improve them ap
