The magnetoresistive sensors in a gradiometric configuration are sensing the vertical component of a magnetic field - either originating from magnetized ferromagnetic bodies or induced by 1-kHz, alternating continuous-wave excitation. The AMRs are arranged so that the electronics can suppress the homogeneous Earth field and the large excitation field. The mine-detector was in first constructed as a standard handheld device. The presented results show that the performance is limited by the noise of the selected magnetoresistive sensor. If the size of the sensor array was increased, the system could form an advanced towed-mine-detector for quick, large-scale demining purposes." . "192557" .
