Abstract
Provided is an FMCW radar device capable of reducing pairing errors. With use of a first peak frequency change rate during a first chirp period and a second peak frequency change rate during a second chirp period, a first temporary range during the first chirp period and a second temporary range during the second chirp period are calculated. When a difference between the first temporary range and the second temporary range is equal to or less than a set threshold, a first peak frequency and a second peak frequency in a current processing period are paired with each other.
