5203 |a"The detection of buried mines is a problem of prime interest internationally. One potential method to succeed in this task is to use passive IR imaging to form thermal images of the soil surface. Even though this technique has been intensively investigated [...], only few publicly reported studies show quantitative measures of the apparent temperature contrast at the soil surface above buried mines. This document aims to improve that situation. Apparent temperature contrasts are measured for different mine-soil combinations over 24 hours periods with a camera sensitive to long wave infrared (8-12 nanometers). The effect of the variation in burial depth is investigated and special attention is taken to differentiate the thermal effect associated with the soil disturbance from the mine itself. [...]. Results are promising, however, serious reservations about an acceptable false alarm rate and the duration of the thermal effect created by the soil disturbance are expressed"-- Abstract (page iii).
