Claim 8:
9. The radar detector according to claim 4, further comprising:
a digital-to-analog converter configured to convert the interference estimation signal from a digital form into an analog form,
wherein a first receiving end of the subtractor or the subtraction circuit is coupled to an output end of a frequency mixer of the radar receiving device, and a second receiving end of the subtractor or the subtraction circuit receives the interference estimation signal in the analog form,
in response to the first wireless signal is not subdued from being transmitted, the first receiving end of the subtractor or the subtraction circuit receives an analog receive signal from the output end of the frequency mixer, and the subtractor or the subtraction circuit subtracts the interference estimation signal in the analog form from the analog receive signal to generate a processed analog receive signal as the analog main signal,
and the analog-to-digital converter converts the analog main signal into the digital main signal.
