Radar system and computer program

A radar system comprising:

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