AbstractThe goal of this project is to design, build, and test an active electromagnetic induction (EMI) sensor array for detecting and characterizing IEDs. At low frequencies (below a few kHz), an EMI sensor is a magnetometer that primarily responds to susceptibility targets (i.e., ferrous objects). The main difference is that, while a magnetometer uses the earth’s field as the illuminating source, an EMI sensor emits its own time-varying magnetic field and, thus, has the name electro-magnetometer. During Phase II, we will design and build a new 7-channel GEM-3 array with a 2.4-m swath; modify the driver electronics for an increased number of channels; increase the sampling rate up to 750 Hz for higher vehicle speeds; conduct indoor/outdoor tests at Geophex; develop and build, in co-operation with the ARDEC staff, sensor-mounting contraptions for a candidate vehicle; conduct demonstration surveys at ARDEC on a moving vehicle.
