AbstractImproved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internetted ground sensors, as well as from UAV. The improved generic sensors will find numerous applications for diverse types of tunnel detection problems using passive and active techniques as well as for detecting activities in the tunnel. The improvements will be made in terms of stability, ruggedness, compactness, low-power requirements, as well as for superior noise cancellation and signal processing schemes. Complete digital system is proposed to attain the desired characteristics.
