    • PROBLEM TO BE SOLVED: To provide a radar device capable of acquiring target information highly accurately.
      SOLUTION: This radar device of an FMCW system generates snapshot data from a beat signal showing a reception result in each modulation period. Then, each autocorrelation matrix in each modulation period generated from snapshot data in each modulation period is averaged as many as a plurality of period portions, and a target azimuth is determined by MUSIC method based on the averaged autocorrelation matrix. In this case, averaging is performed by a weighted mean method based on the amount (interference amount) of noise components included in the snapshot data in each modulation period. Namely, a weighting coefficient to be applied to the autocorrelation matrix in each modulation period is set at a value corresponding to the interference amount of the modulation period (S570). When the interference amount is small, the weighting coefficient is set high, and when the interference amount is large, the weighting coefficient is set low.
