A radar device including a frequency peak detection unit for receiving reflected waves from objects, a first combination group determination unit for combining up frequency peaks with down frequency peaks, a first pairing candidate group determination unit for calculating a Mahalanobis distance for each combination, a second combination group determination unit for combining down frequency peaks with up frequency peaks, a second pairing candidate group determination unit for calculating a Mahalanobis distance, a pairing candidate group extraction unit for removing the pairs having larger Mahalanobis distances, a current pairing candidate group determination unit for removing the pairs having a Mahalanobis distance larger than or equal to a threshold value, and a current data calculation unit for calculating current data values that include a distance, relative velocity and angle of the objects. The characteristic values include angles, power and spectrum intensity.
