Recognition technology for the detection of buried land mines

As described by Zadeh, recognition technology refers to systems that incorporate new sensors, novel signal processing, and soft computing. In this paper, we discuss these principles as they apply to the serious problem of land mine detection. We describe a complex recognition system that is evolving from basic research into a Fielded system. Some components of this system have been field tested with excellent results, whereas other components have achieved such results in the laboratory. Fuzzy set-based information fusion algorithms are central to the excellent results obtained. Multiple-detection algorithms are applied to signals acquired from an innovative ground penetrating radar (GPR) that produces volumetric subsurface imagery. The outputs of the detection algorithms are combined using fuzzy logic and the Sugeno and Choquet fuzzy integrals to produce overall detection scores. Experimental results are provided on training data and on completely blind test data collected in the field and scored by the U.S, Army.
