“…Most if not all of these sensors are affected to some degree by soil conditions (Das et al 2003; table 1). The performance of a sensor under specific soil conditions can be predicted using a thorough understanding of the physics of the soil-mine-sensor system.…”

“…Although research on how to detect and dispose of landmines started in the early half of the 1900s (BWO 1947, Das et al 2003, the field of humanitarian demining is only some 20 years old. In recent years, the case for a landmine free world has become stronger, but serious efforts are still needed to develop new and improve existing technologies that can help in identifying landmine fields, and in detecting and clearing the landmines (MacDonald et al 2003).…”

Most sensors for the detection of buried landmines are influenced by the properties of the soil that surrounds the mine. The temporal and spatial variability in soil properties accounts for a significant part of the detection uncertainty that is associated with most sensors. In particular, most sensor types (e.g. ground-penetrating radar, thermal infrared cameras, and chemical sniffers) are affected by the water content of the soil. However, each sensor type reacts in its own way to variations in soil water content and other soil properties. The resulting variation in sensor performance has serious implications for sensor fusion operations. We show how knowledge of soil physics can contribute to a better understanding of sensor performance and can lead to improved data fusion.

The Geotechnical and Structures Laboratory at the US Army Corps of Engineers, Engineer Research and Development Center (ERDC) has developed a near-surface properties laboratory to provide complete characterization of soil. Data from this laboratory is being incorporated into a comprehensive database, to enhance military force projection and protection by providing physical properties for modelers and designers of imaging and detection systems. The database will allow cross-referencing of mineralogical, electromagnetic, thermal, and optical properties to predict surface and subsurface conditions. We present an example data set from recent collection efforts including FTIR in the Near-IR, MWIR, and LWIR bands, magnetic susceptibility (500 Hz to 8 GHz), and soil conductivity and complex permittivity (10 μHz to 8 GHz) measurements. X-ray data is presented along with a discussion of site geology, sample collection and preparation methods, and mineralogy. This type of data-collection effort provides useful constraint information of soil properties for use in modeling and target detection. By establishing real ranges for critical soil properties, we are able to improve algorithms to define anomalies that can indicate the presence of land mines, unexploded ordnance (UXOs), improvised explosive devices (IEDs), tunnels, and other visually obscured threats.

“…Several studies in the past have addressed the influence of variability in soil texture and soil water content on electromagnetic sensors for the detection of land mines 4,5 . The study of magnetic soil properties in relation to the problem of land mine and UXO detection is relatively new 6,7,8,9 . Also, little is known about the natural variability in magnetic characteristics of soils.…”

The presence of magnetic iron oxides in the soil can seriously hamper the performance of electromagnetic sensors for the detection of buried land mines and unexploded ordnance (UXO). Previous work has shown that spatial variability in soil water content and texture affects the performance of ground penetrating radar and thermal sensors for land mine detection. In this paper we aim to study the spatial variability of iron oxides in tropical soils and the possible effect on electromagnetic induction sensors for buried low-metal land mine and UXO detection. We selected field sites in Panama, Hawaii, and Ghana. Along several horizontal transects in Panama and Hawaii we took closely spaced magnetic susceptibility readings using Bartington MS2D and MS2F sensors. In addition to the field measurements, we took soil samples from the selected sites for laboratory measurements of dual frequency magnetic susceptibility and textural characteristics of the material. The magnetic susceptibility values show a significant spatial variation in susceptibility and are comparable to values reported to hamper the operation of metal detectors in parts of Africa and Asia. The absolute values of susceptibility do not correlate with both frequency dependence and total iron content, which is an indication of the presence of different types of iron oxides in the studied material.
