Abstract

Disclosed herein is a frequency modulated continuous wave (FMCW) radar. The FMCW radar includes: a transmission signal generator that generates a frequency-modulated transmission signal; a transmission signal sender that sends the transmission signal; a receiver that receives a reflected wave of the transmission signal; an adjuster that adjusts the amplitude and phase of a cancel signal, which cancels a leakage signal component in a received signal, in accordance with a variation in the frequency of the transmission signal; and a superimposer that superimposes the cancel signal over the received signal to cancel the leakage signal component.
