This paper presents an experimental design and the evaluation result of a trial that were carried out from 1 February to 9
March 2006 using real PMA-1A and PMA-2 landmines at the Benkovac test site in Croatia. The objective of the Croatia-
Japan joint trial is to evaluate dual sensor systems, which use both ground penetrating radar (GPR) and electromagnetic
inductive (EMI) sensors. A comparative trial was also carried out by Croatian deminers using an existing EMI sensor,
i.e., a metal detector (MD). The trial aims at evaluating differences in performance between dual sensors and MDs,
especially in terms of discrimination of landmines from metal fragments and extension of detectable range in the depth
direction. Devices evaluated here are 4 prototypes of anti-personnel landmine detection systems developed under a
project of the Japan Science and Technology Agency (JST), the supervising authority of which is the Ministry of
Education, Culture, Sports, Science and Technology (MEXT). The prototypes provide operators with subsurface images,
and final decision whether a shadow in the image is a real landmine or not is left to the operator. This is similar to the
way that medical doctors find cancer by reading CT images. Since operators' pre-knowledge of locations of buried
targets significantly influences the test result, three test lanes, which have 3 different kinds of soils, have been designed
to be suitable for blind tests. The result showed that the dual sensor systems have a potential to discriminate landmines
from metal fragments and that probability of detection for small targets in mineralized soils can be improved by using
GPR.

This paper discusses an experimental design method for test and evaluation of anti-personnel landmine detection systems using ground penetrating radar (GPR). Vehicle-mounted mine detection systems to be evaluated here have been developed by six research teams from universities and industries founded by Japan Science and Technology Agency. Sensors used are a GPR and electromagnetic induction (EMI) fused type, which provides underground images to operators. In our basic concept, the systems make no explicit alarm and the final decision whether or not a shadow in the image is a real landmine is left to the operator. This is the same way as medical doctors find cancer by reading CT images. To test these kinds of systems, i.e., to evaluate probability of detection (PD), false detection rate, and other characteristics, seven test lanes using more than 200 landmine surrogates has been designed. Since operators' pre-knowledge of the locations of buried targets significantly influences the detection results in our systems, six out of the seven test lanes are designed to be suitable for blind tests. A comprehensive test and evaluation using the designed experimental lanes is in progress for over one month, and some results obtained from the test are discussed.
