Claim Text:
1. A radar device comprising: a generating unit that generates a frequency spectrum from a beat signal corresponding to a predetermined period “t;” an estimating unit that estimates (i) a distance and a relative velocity of a target in the predetermined period “t” based on the distance and the relative velocity of the target in a past period “t−1,” which precedes the predetermined period “t,” and (ii) estimates a peak frequency corresponding to the target in the predetermined period “t” based on the distance and the relative velocity estimated by the estimating unit; and a determining unit that determines, with respect to the frequency spectrum generated by the generating unit, a frequency equal to the estimated peak frequency in the frequency spectrum generated by the generating unit is a peak frequency corresponding to the target in the predetermined period “t” when power corresponding to the estimated peak frequency in the frequency spectrum generated by the generating unit is equal to or higher than a first predetermined threshold, wherein
