A two-step process for clearing unexploded ordnance ("UXO") from the ground. First a high power electromagnetic transmitter sweeps the ground area to be decommissioned. Secondly a lower-power time-domain electromagnetic transmitter or metal detector sweeps the same area to locate UXO. The high power transmitter employs a waveform of having the same frequency and pulse duration as that of the metal detector but does so with at least twice the power. Firstly, when the higher power waveform is applied to the ground, UXO which does not trigger and detonate or "function" is proved as n on- functioning at subsequent and lower detection power. Subsequently, the groun d area can then be safely scanned by human personnel with impunity, applying t he more accurate, lower power metal detector. The detected locations of unexploded ordnance are recorded for subsequent manual removal. |
