Abstract: There is provided a radar apparatus. A first determining section is configured to determine whether there exists a continuing stationary target at a side of a lane in which a vehicle is traveling. A second determining section is configured to determine whether there exists a moving target in a specific range which is in front of the vehicle and on an opposite side of the stationary target with respect to a position of the vehicle. A changing section is configured to change position information of the moving target to a position obtained by folding back a specific position which is the position of the moving target in the specific range with the stationary target therebetween in a case where the stationary target exists and the moving target exists in the specific range. The changed position is used for deriving the position information of the target.

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.

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: There is provided a radar apparatus. A derivation unit derives this time-decided transverse distance of the target of this time processing, by filtering, with a predetermined filter constant, this time transverse distance of paired data of this time processing, and a predicted transverse distance. A change unit changes, when the transverse distance of an object moving target moving in a traveling direction of a vehicle mounted with the radar apparatus and the transverse distance of a specific target satisfy a predetermined relation, the filter constant for filtering this time transverse distance and the predicted transverse distance of the object moving target so that a reflection amount of this time transverse distance is reduced in comparison to before the change.
