1. A method of generating a radar threshold associated with a radar, comprising:

  • transmitting a plurality of radio frequency (RF) signals;

    receiving a plurality of composite signals, each composite signal including at least one of a received RF signal and a noise signal;

    converting the plurality of composite signals to provide a plurality of baseband signals;

    transforming the plurality of baseband signals to the frequency domain to provide a respective plurality of frequency domain signals, each one of the plurality of frequency domain signals having a corresponding plurality of frequency domain values and a respective plurality of frequency bins;

    computing a first plurality of percentile values from the plurality of frequency domain values associated with at least two of the plurality of frequency domain signals; and

    generating a detection threshold associated with the first plurality of percentile values.
