Abstract: There is provided a radar device. An estimating unit estimates peak signals corresponding to a target in the latest periods of each of UP and DOWN beat sections of a beat signal on the basis of histories of peak signals corresponding to the target in past periods of the UP and DOWN beat sections. A pairing unit extracts peak signals within predetermined ranges defined with reference to the estimate peak signals on the basis of the histories, and pairs the extracted peak signals. In a case where a distance to the target is equal to or shorter than a predetermined value, the pairing unit extracts peak signals corresponding to the target, from a first range which is a predetermined angular range defined with reference to the estimate peak signals, or a second range which is a predetermined transverse position range defined with reference to the estimate peak signals.

Abstract: There is provided a radar device that calculates an angle of a target based on a phase difference between reception signals obtained by receiving reflected waves from the target. A transmitting unit alternately transmits first and second transmission waves having different beam patterns. A calculating unit calculates reception levels of the reception signals, and an estimate angle at which the target is estimated to exist. A first determining unit determines a degree of reliability of a level difference between the reception levels, on the basis of a comparison between the level difference with a reference value which is associated with the estimate angle in advance. A second determining unit determines whether the target exists at the estimate angle, on the basis of a determination result and the reception level based on the first transmission wave.

Abstract: A radar apparatus is configured to set a first target to be a non-output object with respect to a control apparatus of a host vehicle in a case where the first target (1) has a fore-and-aft distance from the host vehicle that is larger than a fore-and-aft distance from the host vehicle of a second target and (2) has a predetermined dependency to be an accessory portion which belongs to a same vehicle as the second target. The radar apparatus includes a signal processor configured to: determine whether or not the second target is present in an own lane of the host vehicle; determine whether or not the second target is changing a lane; and set the first target to be an output object with respect to the control apparatus of the host vehicle in a case where the second target is changing the lane from the own lane.

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: There is provided a radar apparatus capable of emitting a transmission wave relating to a transmitting signal which is frequency-modulated, and receiving a reflection wave coming from a target at which the transmission wave is reflected as a receiving signal, to derive at least position information of the target based on the receiving signal. A deriving unit derives a fluctuation value of a signal level relating to the receiving signal for a stationary target among the targets. A calculating unit calculates a fluctuation integrated value integrated by the fluctuation value. A judging unit judges the stationary target as a target other than a control subject if the fluctuation integrated value is below a predetermined threshold.
