In this paper, the characterization of the electromagnetic soil properties of a blind lane used in a trial for a dual-sensor mine detector is presented. Several techniques are used and are compared here; Time Domain Reflectometry, gravimetric techniques and Frequency Domain Reflection and Transmission methods. The derived soil properties are mapped by interpolation and the resulting maps are compared with the recorded deminers' performance on the lane. Recurrent and non-predicted results from the performance of the dual-sensor detector are explained as the results of variability of certain properties.
In this paper results are presented of a study on the performance of a dual-sensor landmine detector and its dependency on soil moisture. The detector was used on a trial site in the K5 mine belt in Cambodia. Soil samples were taken from the trial lane, as well as GPR measurements. The data obtained from these soil samples and field measurements are integrated into a model for soil moisture content that is correlated with the land mine detector performance.
