3.4.CORE SKILL 3 – USE OF DETECTORS IN IED SEARCH Initially, mine detectors in mine action focused on the requirement for the sensor to be capable of reliably detecting anti-personnel mines with a specific metal content to a set depth. Now, a multitude of sensors exist that can detect the presence of other materials and anomalies that may indicate the presence of an item of EO. These sensors include ground penetrating radar (GPR), which detects subsurface cavities or differences in material between an item and the ground around it. Other sensors include those for the detection of long and short wires and even carbon rods. Selecting the detector type for IED search should be initially based on the national threat analysis and clearance criteria set by the NMAA or an equivalent body. This will help ensure that detectors purchased and imported to facilitate a programme will provide the capability needed by the programme. The selection process should include conducting a cost benefit analysis, as spending more money on enhanced detectors could be offset by a reduction in labour costs, while achieving a greater level of output. This should be confirmed during site specific operational threat assessments, to ensure that the situation has not changed.
