A radar detector is comprised of a voltage controlling oscillator (VCO) instead of DROs, thereby decreasing the cost of radar detector. The radar detector comprises a voltage controlled 1st local oscillator generates a signal of a frequency of 11.2796 GHz to 11.9832 Ghz, two (2) 2nd local oscillators generate signals with frequencies of 0.603 GHz and 1.3668 GHz, a memory section which stores pair combination data indicating the relation between the frequency of said voltage controlled oscillator, the frequencies of said local oscillators and the frequency of the received radar signal in advance; and a controlling section which decides the frequency of a radar signal by comparing the obtained information with said pair combination data.
