Detection of buried explosives

Patent Granted In cases of unexploded subsoil ordnance a remote investigation is done by visual interpretation of available historical aerial photographs. Modern techniques can combine geophysical and survey methods with modern electromagnetic and magnetic detectors. This provides digital mapping of UXO contamination with the aim to better target subsequent excavations, reducing the cost of digging on every metallic contact and speeding the clearance process. Magnetometer probes can detect UXO and provide geotechnical data before drilling or piling is carried out.
