Abstract
An in-vehicle radar device includes: phase storing means 12 that prestores the phase of a received wave incoming secondarily from outside a target; received wave importing means 13 that imports the received wave on the basis of a radio wave reception timing determined by a transmission timing of the radio wave; phase detecting means 14 that determines the phase of the received wave imported by the received wave importing means; phase correction amount extracting means 15 that compares the phase prestored by the phase storing means 12 with the phase detected by the phase detecting means 14 and extracts and stores a phase correction amount of each of element antennas; and phase correcting means 16 that corrects the phase of a received signal of each of the element antennas on the basis of the phase correction amount obtained by the phase correction amount extracting means.
