Claim 10:
11. The radar detector according to claim 10, wherein the radar receiving device comprises:
a receiving antenna end receiving the second wireless signal as a first analog signal in response to the first wireless signal is subdued from being transmitted, and receiving the third wireless signal as the first analog signal in response to the first wireless signal is not subdued from being transmitted;
a low noise amplifier coupled to the receiving antenna end and amplifying the first analog signal to form an amplified analog signal; and
a frequency mixer coupled to the low noise amplifier and the local oscillator in the radar transmitting device, wherein the frequency mixer performs down-conversion frequency mixing on the amplified analog signal according to the carrier frequency of the first wireless signal from the local oscillator, so as to generate the analog reference signal in response to the first wireless signal is subdued from being transmitted, and generate the analog main signal in response to the first wireless signal is not subdued from being transmitted.
