STEPPED-FMCW WAVEFORM APPLIED FOR MM-WAVE AUTOMOTIVE COLLISION WARNING RADAR

A stepped FMCW radar waveform applied for mm wave automotive collision warning radar systems was proposed, which is easy to be generated digitally and its signal processing reduced the requirement of computational speed compared to conventional hgih resolution radars. An error approach algorithm was suggested for multiple vehicle target detection and its usefulness in eliminating the false target by computer simulation was confirmed.
