Standardized UXO Technology Demonstration Site Scoring Record No. 932. EM63/Pushcart
Abstract
This scoring record documents the efforts of US Army Engineering Research and Development Center (ERDC) to detect and discriminate unexploded ordnance (UXO) utilizing the APG Standardized UXO Technology Demonstration Site blind grid, open field and active sites. The EM63 is a commercially available sensor. It is a high power, high sensitivity, wide bandwidth full-time domain UXO detector. The EM63 consists of a powerful transmitter that generates a pulsed primary magnetic field which induces eddy currents in nearby metallic objects. The time decay of the currents is accurately measured over a wide dynamic range of time. The output of the main sensor is measured and recorded by the main console at 20 to 30 geometrically spaced time gates, depending on the used repetition rate, covering a time range from 180 micro s to 63 ms. The second receiver coil, axially mounted is either free running or controlled by wheel odometer or manual fiducial. The EM63 system consists of three major hardware subsystems: 1) EM63 Control Console Subsystem, 2)Antenna Cart Subsystem, 3) Global Positioning System (GPS) Navigation Subsystem.
