ABSTRACT:
A radar system comprises: a plurality of reception antennas; a transmission wave generating device; a transmission antenna; a mixer; an A/D converter; a storage device which stores the digitized beat signals in association with each of the reception antennas; a Fourier transformation device which Fourier transforms the stored beat signals; a digital beam forming device which generates beam signals at predetermined pitch angles based on the Fourier transformed signals; an orientation detecting device which detects an orientation of the object using the generated beam signals; a distance detecting device which detects a distance to the object using the generated beam signals; and a signal separation processing device which performs separation processing of the beat signals based on the detected orientation and distance of the object, using the beat signals associated with each of the reception antennas, which are Fourier transformed by the Fourier transformation device.
