PROBLEM TO BE SOLVED: To improve accuracy of interference determination with another radar in an FMCW radar. SOLUTION: A peak frequency component exceeding an excessive determination value is detected in a high frequency domain having a higher frequency than a detection frequency domain corresponding to a detection range of a target based on a result acquired by performing frequency analysis of sampling data of an over-sampled beat signal (S210). A range of a frequency width fd having a frequency of the detected peak frequency component as a center is set as an excessive domain (S230), and a mean value of signal intensities on a pair of domain edges in the excessive domain is determined as an interpolation value in each set excessive domain, and after replacing signal intensities of all the frequency components belonging to the excessive domain with the interpolation value (S240), each intensity of the frequency components in integrated over the whole high frequency domain (S250), and existence of interference with another radar is determined based on the integrated value.
