  • Interleaved sweep for detection of pop transmissions in police radar detectors
    Patent number: 7061423
    Abstract: In a police radar detector, a sweep signal defines at least one first sweep signal and at least one second sweep signal with the at least one second sweep signal being seamlessly inserted into the first sweep signal so that the first sweep signal is interrupted during the second sweep signal and restored after completion of the second sweep signal so that the first sweep signal can be continued. The frequencies swept by the at least one second sweep signal are thus overswept. By assigning the frequencies swept during the at least one first sweep to the radar bands of interest and the frequencies swept during the at least one second sweep to the frequencies used in the POP mode of operation by police radar, the short bursts of energy used in the POP mode can be detected.
