1. A method for processing radio frequency signals, comprising:

  • transmitting a first transmitted calibration radio frequency (RF) signal into a background environment in which no targets are present;

    receiving a first received calibration (RF) signal associated with the first transmitted calibration RF signal, the first received calibration RF signal reflected from the background environment and indicative of the environment in which no targets are present;

    generating a first threshold signal based at least in part on the first received calibration RF signal;

    transmitting a second transmitted operation RF signal;

    receiving a second received operation RF signal associated with the second transmitted RF signal; and

    generating a display based on, at least in part, the first threshold signal and the second received operation RF signal.
