Abstract
A radar device includes: a first radar and a second radar to transmit, as radar signals, frequency modulated signals whose frequency gradients with a lapse of time are different from each other and receive reflected waves of the radar signals; a calculation unit to calculate a first frequency spectrum obtained by performing Fourier transform in a distance direction on digital data of a beat signal and a second frequency spectrum obtained by performing Fourier transform in a relative velocity direction on the first frequency spectrum, and calculate distance and velocity information for each radar on the basis of a beat frequency and a Doppler frequency corresponding to a peak value in the second frequency spectrum; and a processing unit to compare the distance and velocity information calculated for each of the radars.
