摘要： PROBLEM TO BE SOLVED: To improve the detection accuracy of a target existing in a near distance.SOLUTION: A rader device includes a generating portion, an estimating portion, and a determining portion. The generating portion generates a frequency spectrum from a beat signal corresponding to a predetermined period. The estimating portion estimates a peak frequency corresponding to a target on the basis of position information of the target corresponding to a past period. The determining portion determines whether the peak frequency is a peak corresponding to the target or not by comparing power near the peak frequency estimated by the estimating portion with a predetermined threshold value, concerning the frequency spectrum corresponding to a latest period.
