COMPACT, AUTONOMOUS ROBOTIC DETECTION AND IDENTIFICATION SENSOR SYSTEM OF UNEXPLODED ORDNANCE SITE REMEDIATION

摘要

A device operative to detect metal objects. The device includes a transmitter circuit, an upper transmitter coil and a lower transmitter coil operatively connected to the transmitter circuit. A current fed through the upper transmitter coil and the lower transmitter coil generates a field that excites eddy currents in metal objects in the vicinity of the upper transmitter coil and the lower transmitter coil. An upper magnetic field detector and a lower magnetic field detector are operative to sense eddy currents generated in the metal objects. Processor elements operatively connected to the upper magnetic field detector and the lower magnetic field detector collect, store and analyze the eddy currents and thereby determine the likelihood that a metal object has been detected. A navigation system operatively connected to the processor elements controls movement of the device. Transporting elements operatively connected to the navigation system are operative to support the device and permit alteration of a position of the device.
