Abstract: A radar detector includes an antenna for receiving a first signal of ultrahigh-frequency, a first local oscillator oscillating a second signal, a first filter removing noise from the second signal oscillated via the first local oscillator, a first mixer mixing the first signal of ultrahigh-frequency with a third signal filtered via the first filter, an intermediate frequency amplifier amplifying a fourth signal mixed at the first mixer, a second local oscillator oscillating a fifth signal, a second mixer mixing a sixth signal amplified via the intermediate frequency amplifier with the fifth signal oscillated by the second local oscillator, a second filter filtering a seventh signal mixed at the second mixer, a demodulator converting analog values of an eighth signal filtered by the second filter into digital values, a memory part storing data of relations between a ninth signal converted via the demodulator and the second and fifth signals oscillated by the first and second local oscillators, a central proces
