Abstract:
A metal detector detects when a target that is a desirable metal object is located within a medium. A signal is transmitted into the medium. A response signal is received from the medium. The response signal includes a secondary medium response signal from the medium and includes a secondary target response signal from the target when the target is located within the medium. The response signal is amplified to produce an amplified signal. Compensation circuitry perform transmit coil transfer function compensation on the amplified signal to produce a compensated signal. A notch module removes a resistive component of the secondary medium response signal from the compensated signal. A signal vector resistive component demodulator produces a vector resistive component output signal from output of the notch module. A vector reactive component demodulator produces a vector reactive component output signal from the output of the notch module. Output from the signal vector resistive component demodulator and the signal vector reactive component demodulator is digitized to produce digital signals. A digital signal processor processes the digital signals.
