1. A wireless communications device configured to detect radar signals, comprising:

  • a receiver having a Fast Fourier Transform (FFT) unit for receiving an incoming signal, wherein the FFT unit generates a first FFT capture including a signal magnitude for a plurality of frequency bins; and

    a radar unit configured to;

    perform an initial signal analysis on the first FFT capture;

    identify a candidate radar signal based at least in part on whether the signal magnitude of at least one of the frequency bins exceeds an initial threshold;

    perform a secondary signal analysis on the incoming signal; and

    determining the candidate radar signal is a false detection based at least in part on the secondary signal analysis.
