Abstract
A radar apparatus is provided to receive a transmission wave reflected by a target object by antennas. The radar apparatus includes a signal analysis unit to analyze reception waves, and to obtain amplitudes and phases of the reception waves, at a frequency with which reception strength shows a peak. The radar apparatus also includes a direction detection unit to detect a direction of the target object based on the phases of the reception waves, and an estimated amplitude and phase output unit to output estimated amplitudes and estimated phases of reception waves to be received, assuming that the target object exists in the detected direction. The radar apparatus further includes a comparison unit to compare the amplitude or phase obtained by the signal analysis unit with that output by the estimated amplitude and phase output unit.
