Abstract: A radar apparatus mounted on a moving body includes a signal transceiver that receives one or more radar signals reflected by one or more second reflection points of one or more targets located in a scan range with a plurality of antennas, detection circuitry that detects an azimuth angle of the one or more second reflection points of the one or more targets on the basis of a correspondence between a phase difference among the plurality of antennas and an azimuth angle and a phase difference observed in the scan range among the plurality of antennas, calculation circuitry that selects the one or more second reflection points located in a second range that differs from a first range including a central axis on which the phase difference among the antennas is zero and calculates a second azimuth angle error, and correction circuitry that corrects the correspondence.
