PURPOSE: A device and method for receiving a radar capable of correcting a noise gain by using a DVA(Digital Variable Attenuator) are provided to secure the dynamic area of the radar and secure the linearity of a signal process. CONSTITUTION: A DVA(110) receives fed back control signal for controlling the attenuation amount of a received signal and attenuates the received signal by using the fed back control signal. An ADC(Analog-to-Digital Converter)(120) converts the attenuated signal into a digital signal. A digital signal processor(130) calculates the noise amount of the received signal from the digital signal and generates a control signal for controlling the attenuation amount of the received signal by using the calculated noise amount.
