description A method for detecting a target in a soil using a metal detector, including: generating a transmit magnetic field for transmission into the soil based on a transmit signal; receiving a receive magnetic field; providing a receive signal induced by the receive magnetic field; determining, based on the receive signal, a model of at least two independent components of the receive signal which are due to signals from the soil; processing the receive signal to produce a set of data which is with effects of the signals from the soil reduced therein or removed therefrom by fitting the model to the receive signal, then subtracting the fitted model from the receive signal; and producing, based on the set of data, an indicator output signal for indicating a presence and/or identity of the target.
