Abstract: According to an embodiment, there is provided a radar device including a generating unit, an estimating unit, and a determining unit. The generating unit generates a frequency spectrum from a beat signal corresponding to a predetermined period. The estimating unit estimates a peak frequency corresponding to a target on the basis of location information of the target corresponding to a past period. The determining unit determines, with respect to the frequency spectrum corresponding to the latest period, whether the peak frequency is a peak corresponding to the target by comparing power near the peak frequency estimated by the estimating unit with a predetermined threshold.

Abstract: There is provided a radar apparatus. An extracting unit extracts a peak signal obtained from a difference frequency between a transmitting signal and a receiving signal during a first period in which the frequency of the transmitting signal ascends and a second period in which the frequency descends. A pairing unit pairs the peak signals of the first and second periods based on a predetermined condition. A deriving unit derives target information including a position of a target based on paired data obtained by pairing the peak signals. The pairing unit selects normal-paired data which is paired in a correct combination, from among the plurality of paired data, based on a plurality of parameter values of the peak signals of the first and second periods which are to be paired, and a discrimination function for discriminating true or false of the pairing.

Abstract: A radar device according to an embodiment includes a transmission unit, a reception unit, a processing unit, a first determination unit, and a second determination unit. The transmission unit emits transmission signals. The reception unit receives reception signals acquired by reflecting the transmission signals on an object. The processing unit detects object data corresponding to the object from the reception signals. The first determination unit determines object data included in a predicted range based on past object data detected in the past as past correspondence data having time continuity with respect to the past object data. In a case where parameters of new data that has not been detected in the past and the past correspondence data have predetermined relation, the second determination unit determines that the new data and the past correspondence data correspond to the same object.
