Abstract: A FMCW radar apparatus obtaining information about a target object includes: a transmitter generating a transmission signal of which frequency is modulated based on the FMCW method, the receiver receiving the radar waves reflected at the object, a mixer that generates a beat signal from a mixed signal of the received signal and the transmission signal, and a signal processing unit processing the beat signal to obtain the information including a distance between the own vehicle and the target object, and a relative velocity of the target object. The signal processing unit includes first calculating means and second calculating means, which operate in parallel each other to calculate the information about the object based on the beat signal from an upward-modulation period when the frequency is modulated to be increased and from a downward-modulation period when the frequency is modulated to be decreased respectively.
