Abstract
A radar device includes a mixer that mixes an output of a transmit antennaand an input of a receive antennaan LPFan A/D converterthat samples an output signal of the LPFand subjects the sampled signal to A/D conversion, an FFT processing devicethat subjects the converted signal to high-speed Fourier transformation, an aliasing discriminating/correcting device that discriminates a signal having a frequency component where aliasing occurs from a result by the FFT processing deviceand corrects the signal to a signal of a normal frequency component where no aliasing occurs to obtain a distance and relative velocity data of the object, and a target object selecting device that selects necessary data from the distance and relative velocity data of the object which are obtained from the aliasing discriminating/correcting means.
