1. A radar apparatus in which light is emitted into a search region by an emission unit that emits light, the light being reflected by an object in response to the emitted light being received by a light receiver, and, at least, a distance to the object is detected based on the received reflected light, the radar apparatus comprising:
a light emission instructing unit being configured to instruct the emission unit to emit light into the search region; and
determination unit being configured to acquire an own vehicle information representing information indicating movement of an own vehicle, and based on the own vehicle information, the determination unit determines whether the own vehicle is performing at least one designated movement representing the movement of the own vehicle traveling in a direction deviated from a forward direction of the own vehicle by a predetermined angle, and wherein,
the search region is divided into a plurality of divided regions, each of the plurality of divided regions being defined by the predetermined angle,
the light receiver is configured to receive reflected light at different timings for each of the plurality of divided regions,
the light emission instructing unit is configured to reduce at least one of a number of times of emission, an emission frequency, and an emission intensity for a designated region, when the own vehicle is performing the at least one designated movement compared to when the own vehicle is not performing the at least one designated movement, the designated region indicating at least one of the plurality of divided regions, and
the light emission instructing unit is configured to cause the emission unit to emit light depending on the at least one of the number of times of emission, the emission frequency, and the emission intensity that is set for the designated region.
