Abstract
An in-vehicle radar device includes: phase storing meansthat prestores the phase of a received wave incoming secondarily from outside a target; received wave importing meansthat imports the received wave on the basis of a radio wave reception timing determined by a transmission timing of the radio wave; phase detecting meansthat determines the phase of the received wave imported by the received wave importing means; phase correction amount extracting meansthat compares the phase prestored by the phase storing meanswith the phase detected by the phase detecting meansand extracts and stores a phase correction amount of each of element antennas; and phase correcting meansthat 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.
