Newer detectors are growing in capability to discriminate those signals measured over mines from those signals that can be causally related to local variations in the soil. Monitoring and measuring the key properties governing these local variations are being looked at increasingly as a means to predict performance measures for given detectors, as well as to counter the occurrence of such signals in an effort to minimize false alarms. Currently, an ongoing government research project working to develop enhancements to the Handheld Standoff Mine Detection System (HSTAMIDS) technology resulted in a series of data collections acquired in four different types of soil environments: 1) temperate/loamy, 2) temperate/grassy/gravel, 3) arid/gravel/sand, and 4) tropical/laterite. At each of these locations, data was collected using the HSTAMIDS technology to provide a range of environmental conditions against which the performance of this handheld detector could be assessed. This project is obtaining similar electrical and magnetic measurements in these areas to use these measurements to monitor any changes in detection performance that might be introduced due to local soil variations, as well as to provide a preliminary estimate of the robustness of future HSTAMIDS detection enhancements across a variety of environments.
