摘要

PPROBLEM TO BE SOLVED: To provide an FMCW(frequency-modulated continuous wave) radar device for detecting interference from the waves received, and to provide an FMCW radar signal analysis method. PSOLUTION: This signal processing device for the FMCW radar device for performing signal processing of a beat signal of transmission waves and reception waves in the FMCW radar device, is equipped with: an acquisition part for acquiring continuously during a sampling period, K-pieces of first data of a sample, having a length of M which is a beat signal sampled during the sampling period which is one up-beat section or one down-beat section; a first conversion part for performing conversion into a frequency domain of the first data acquired by the acquisition part, and using a conversion result as the second data; and a determination part for determining whether abnormal data which are abnormal second data exist in K-pieces of the second data converted by the first conversion part.
