PROBLEM TO BE SOLVED: To provide a radar device capable of measuring an angle highly accurately under a multipath environment without changing a frequency of a signal to be transmitted/received. SOLUTION: This device is equipped with an aperture separation signal generator 41 for generating an aperture separation signal fromΣbeam andΔbeam generated based on a reception signal; a phase monopulse beam regenerator 42 for regenerating phase monopulse beams each of which comprises theΣbeam and theΔbeam, which are a plurality of phase monopulse beams having an optional orientation direction, based on the aperture separation signal generated by the aperture separation signal generator; a regenerated beam extractor 43 for extracting theΣbeam and theΔbeam in the orientation direction in which output of theΣbeam becomes maximum, from among the plurality of phase monopulse beams regenerated by the phase monopulse beam regenerator; and an angle measurement processor 45 for calculating an angle measurement value by phase monopulse angle measurement by using theΣbeam and theΔbeam extracted by the regenerated beam extractor.
