Abstract: A mine detector has a search head with a transmitting unit for the transmission of signal sequences into the ground, and a metal detection unit. A distance measurement sensor is arranged on the search head for determination of the current geometric distance of the search head from the ground. The response signal sensor and the distance measurement sensor are each connected for dataflow purposes to a measurement data logic unit which can be supplied with ground distance measurement data when the distance between the search head and the ground surface changes, in order to produce a distance/signal strength curve. The measurement data logic unit is connected for data interchange purposes to a curve comparison unit, which is itself connected for data interchange purposes to a standard curve and algorithm storage unit and can be supplied from there with the standard distance/signal strength curves and algorithms.
