A METHOD FOR DISPLAYING METAL DETECTION INFORMATION

摘要

A method for detecting an electrically conductive target in a soil using a metal detector, including: generating a transmit magnetic field for transmission into the soil based on a transmit signal; 5 receiving a receive magnetic field; providing a receive signal induced by the receive magnetic field; processing the receive signal to produce a processed signal; processing a duration of the receive signal, the duration begins after a time the processed signal exceeds a threshold value and ends after a time the processed signal no longer exceeds the threshold value, to produce more than one estimations indicative of a presence of the electrically conductive target when the target is within an influence of 0 the transmit magnetic field; and presenting graphically the more than one estimations.
