MIMEVA: Study of generic Mine-like Objects for R&D in Systems for Humanitarian Demining Executive Summary The MIMEVA project aimed to assess available methods of production of mine simulants and surrogates in terms of the similarity of these replicas to real mines when viewed by a range of sensors identified most frequently as candidates for components in multi-sensor systems, namely: metal detectors, thermal infrared and a ground penetrating radar. The simulant designs resulting from this project may be used to support the testing of new equipment intended to detect anti-personnel (AP) mines – with particular attention to the difficult to find “low- metal content” designs. The main threat mines, affecting areas in where EC humanitarian aid programmes have been undertaken, were identified. In these areas the presence of mines has required action beyond the normal provision of development assistance. Mine types, which pose a post-conflict threat and against which detectors will be required to operate, are listed. Emphasis is placed on South East Europe. Tests that were conducted on surrogates and real mines using three classes of electromagnetic sensor are described. Metal detectors were used to establish the low frequency match between the surrogates and the live mines, radar measurements established the correlation in the microwave region and infrared measurements addressed the thermal properties. A number of surrogate designs were identified including new constructions based on the assembly of commonly available parts. The new designs include air gaps, which are demonstrated to be important in the microwave and infrared regions. Several designs have the possibility to exchange inserts that represent the fuze. It is shown that this is a valuable feature. The results confirm correlation between the electromagnetic features of surrogate mine designs and real mines in the identified spectral regions and thus confirm that the surrogates are appropriate for initial testing of the performance of new mine detection sensors in a controlled manner. The surrogates are completely inert, and are not subject to legal control over their movement allowing them to be used in a wide range of situations. The report is supported by annexes which · Describe the threat mines, · Detail the features of the main high explosives used, · Consider the designs of various surrogate solutions · List possible sources of mine surrogates References used in the compilation of this report are listed to support further investigations.
