Patent ID: 7443167

Claim:
An on-ground detection system for locating subsurface objects beneath a terrestrial surface using both pulsed electromagnetism and magnetometry, the detection system comprising: an on-ground vehicle capable of locomotion on the terrestrial surface; and a mount coupled to the vehicle, the mount including at least one electromagnetic coil transmitting pulses of electromagnetic radiation and to detect electromagnetic radiation resulting from the pulses of electromagnetic radiation to obtain first data indicative of whether any subsurface objects are located beneath the surface at a first location, at least one magnetometer detecting magnetic field information to obtain second data indicative of whether any subsurface objects are located beneath the surface at the first location, and a controller interleaving collection of the second data from the at least one magnetometer with the transmission of the pulses of electromagnetic radiation from the at least one electromagnetic coil, the controller processing the first data and the second data to facilitate determining whether any subsurface objects of interest are present at the first location.
