It is very difficult to estimate depth of a metal object using signal of a traditional eddy-current metal detector which moves in constant distance from the ground we show that : vyhnanek j: distance sensor for mine detector, bachelor thesis supervised by m janosek, czech technical university, prague, 2009 : j roun. The thesis proposes a matched filter approach to detect quadrupole resonance ( qr) signals in the presence of disturbance from am stations detecting qr signals is a challenge due to several reasons one is the amplitude of a qr signal is typically on the same level of thermal noise, which makes it very susceptible to.
