Abstract
A method for detecting radar is provided by the present invention. The invention begins by sweeping a first local oscillator (LO). Once a band has been identified as containing a radar signal, the detector interrupts its normal operation and rechecks the frequency in question for confirmation of CW radar, rather than waiting for the initial sweep to finish. Upon receiving partial information from the initial fast sweep, the detector may repeat this sweep at a slower rate in order to improve sensitivity towards a CW source. If information was from a CW source one can be assured to see the information again when sweeping the same frequency. By contrast, if initial information is from a swept radar detector the information will not be present in the rescan, as the offending radar detector would have moved to a different frequency during the same period of time.
