A novel differential-type magnetic sensor based on the giant magnetoimpedance (GMI) effect, integrating the impedance magnitude and phase characteristics of the amorphous wire due to varying the extern magnetic field, is presented in this paper. The sensor consists of a conditioning circuit based on orthogonal vector lock-in amplifier and differential-type(More)
Magnetic anomaly detection (MAD) is a passive approach for detection of a ferromagnetic target, and its performance is often limited by external noises. In consideration of one major noise source is the fractal noise (or called 1/f noise) with a power spectral density of 1/fa (0<a<2), which is non-stationary, self-similarity and long-range correlation.(More)
