Abstract

Two vehicle mounted metal detector arrays are used in conjunction to perform object classification. The first array (Vallon VMV-16) contains small coils for detecting shallow targets. The second array (Minelab STMR II) contains receive coils of roughly the same size, but a single large transmitter for detecting deep targets. These two sensors are used together to classify objects as: "SHALLOW and LARGE","DEEP and LARGE", or "SHALLOW and SMALL". SHALLOW/DEEP implies the depth of the object; SMALL/LARGE implies the metal content. These object classes are further specified within the paper. An experiment is performed using unexploded ordnance (UXO) and shallow buried calibration objects. The UXO ranges in depth from flush buried to 48". The calibration targets consist of metallic cylinders ranging in depth from flush buried to 12". The strength of each sensor is described and a fusion algorithm is developed. A detection performance curve is shown illustrating the benefit of multi-sensor fusion for UXO detection.
