Sensor Fusion for Hand-held Mine Detection in Investigation Mode
Abstract
In case of hand-held mine detection, the operator functions in two distinct modes. Namely the "scan" mode and "investigation" mode. In scan mode, the operator scans the area to "look" for potential targets. On identifying a suspect target location, the operator switches to investigation mode where he/she "closely" scan the area and tries to identify/discriminate target based on consistency, size and strength of the response. The aim of this paper is to look at the various aspects of sensor fusion in scan and investigation mode to fuse information from a collocated metal detector and ground penetrating radar sensors on a hand-held mine detection unit. Different sensor fusion schemes are compared. It is found that the two sensors are complimentary for a set of mine targets while they are supplementary for other set of mine targets. A better detection performance can be achieved by suitable modification to the sensor fusion scheme based on identified electromagnetic characteristics of detected targets.
