Abstract: On a radar apparatus, a direction derivation part derives a peak angle related to an angle of a target based on reception signals received by a plurality of reception antennas. Then, a detection information derivation part derives, based on the peak angle, target data that are internal data about the target, and stores the derived target data into a memory. A reliability determination part determines a reliability of an object peak angle upon which the target data about the target was derived, the reliability of the object peak angle being determined based on a different peak angle derived concurrently with the object peak angle by the direction derivation part. Then, a data erasure part deletes, based on the reliability of the object peak angle determined by the reliability determination part, the target data relevant to the object peak angle from the memory to exclude the target data from further processing.

Abstract: A radar apparatus includes a signal processor configured to: (i) in a case where a first angle peak signal closest to a prediction position in an up period and a second angle peak signal closest to the prediction position in a down period satisfy a pairing condition, finalize a combination of the first angle peak signal and the second angle peak signal as a pair data set; and (ii) in a case where the combination of the first angle peak signal and the second angle peak signal does not satisfy the pairing condition, where the plurality of angle peak signals exist in the prediction region in at least one of the up period and the down period and where a different combination from the combination of the first angle peak signal and the second angle peak signal satisfies a re-pairing condition, finalize the different combination as the pair data set.

Abstract: There is provided a radar apparatus. A setting unit is configured to set a first range including at least a reference target. A deriving unit is configured to derive a representative position of targets included in the first range on the basis of position information of the targets included in the first range. An acquiring unit is configured to acquire vehicle information indicating that the vehicle is running in a curve-shaped lane or a road shape in front of the vehicle is a curve shape. When the acquiring unit acquires the vehicle information, the setting unit sets a second range wider than the first range and the deriving unit derives a representative position of targets included in the second range on the basis of position information of the targets included in the second range.
