1. A radio transceiver, comprising:

  • radio front end circuitry operable to produce an ingoing communication signal having in-phase and quadrature-phase components on one or more receive signal paths;

    analog-to-digital converter (ADC) operatively coupled to receive the ingoing communication signal, the ADC producing an ingoing digital signal having digital in-phase and quadrature-phase signal components to a signal processor for processing;

    a radar detection block operably disposed within each of the one or more receive signal paths to receive the ingoing digital signal wherein the signal processor inhibits transmission of outgoing digital signals whenever a traditional or non-traditional radar signal has been detected.
