Abstract
We are developing a new hand-held land mine detection dual-sensor (ALIS) which is equipped with a metal detector and a GPR. ALIS is equipped with a sensor tracking system, which can record the GPR and Metal detector signal with its location. It makes possible to process the data after the data was acquired, including migration. The migration processing drastically increases the quality of the images of the buried objects. Evaluation test of ALIS has been conducted in several test sites. In February 2006, a one-month evaluation test was conducted in Croatia, and in October- December 2006, a two-month evaluation test was conducted in Croatia. Since the dual-sensor is a new landmine detection sensor, and the conventional evaluation procedure developed for metal detectors cannot directly be applied for the dual sensor. In Croatia, the detection probability was comparable to that by a metal detector operated by local deminers. In addition, we showed that ALIS provides image of buried objects by GPR, which can be used for identification. Therefore, their performances were sufficiently high. Then the test was also conducted in Cambodia. The test was carried out by 2 local deminers independently, which allows studying the influence of different operators and increases the statistical value of the results.
