Excavator-Mounted Ordnance Locating System for Remote Excavation

This paper presents a novel approach to solving the problem of detecting, locating, and removing buried unexploded ordnance. The locating system consists of an active electromagnetic sensor coil mounted on a backhoe excavator. The system has the unique ability that the coil is capable of eliminating the metallic effect of the backhoe and be lowered into a trench during the digging process. An algorithm can analyze the data from the coil in real time and determine the location of the ordnance.
