Frequency Modulation Continuous Wave (FMCW) radar has been widely used in vehicle safety systems now. Many kinds of waveform have been designed to solve the coupling of distance and velocity in multi-target detection. This paper proposes a novel FMCW waveform which contains three sections with same duration in each period. Two sections are up ramps with different slopes and one is down ramp. Two groups of N*N values of the distance and velocity can be extracted by implementing N-point FFT towards one up ramp and down ramp signal. The distance and velocity in the two groups are the same for the real targets, however, quite different for the ghost targets. Compared with traditional waveforms, the proposed waveform in our work has simpler algorithm and less computation, which has been validated by simulations.
