Abstract
A radar detector is disclosed which comprises a radar wave signal receiver for producing a detection output when the incident radar signal is synchronized with a local oscillation frequency at a certain sweeping time, first and second pulse train signal generators for producing pulses with different cycles, and a cycle alteration circuit for altering the cycle of the second pulse train signal generator in accordance with a logic output corresponding to the detection output from said receiver, thereby synchronizing such cycle with the cycle of the first pulse train signal generator. The regular radar wave signal is discerned by the detection of coincidence between the output pulses from the first and second pulse train signal generators at certain time intervals. Consequently, the radar system is prevented from responding to interference noise or extraneous radar waves.
