  • In this paper, automotive collision warning radar systems which operate on millimeter wave band is introduced first, then a new radar transmit waveform, which can be called multi-slope stepped-FMCW waveform, applied for those systems to solve the false alarm problem is proposed. The new waveform is easy to be generated digitally and its signal processing reduces the high-speed and wide-band signal processing requirement compared with conventional high resolution radar. An error approach algorithm for multiple vehicle target detection is suggested and its usefulness in eliminating the false target is confirmed by computer simulation.
