Multi-mode electromagnetic target discriminator sensor system and method of operation thereof

A method of target discrimination in a multi-mode electromagnetic target discrimination system, comprising the steps of:

• a) setting an antenna, having at least one transmitter coil winding and at least one receiver coil winding, to a frequency domain mode, transmitting frequency domain mode signals, and receiving reflected frequency domain mode signals;
• b) processing in processing circuitry the received frequency domain signals to classify the frequency domain signals;
• c) setting the antenna to a time domain mode, transmitting time domain mode signals, and receiving reflected time domain mode signals;
• d) processing in the processing circuitry the received time domain signals to classify time domain signals;
• e) returning to step a).

A method of target discrimination in a multi-mode electromagnetic target discrimination system, comprising the steps of:

• a) detecting at least one of a frequency domain (FD) signal and time domain (TD) signal from reflected electromagnetic signals;
• b) if a FD signal is detected, classifying the FD signal;
• c) if a TD signal is detected, classifying the TD signal;
• d) comparing the classified FD and TD signals;
• e) outputting the comparison results;
• and,
• f) returning to step a).
