This paper is an investigation of new Frequency-Modulated waveform used in short range radars at 77 GHz in order to detect target with enhanced range and velocity. Two waveforms are proposed: the single and double staircase with equal and different slopes separated by an interval of flat frequency. The single staircase waveform shows an increasing of the range resolution by a factor of 4 compared to a triangular FMCW radar. The velocity resolution is enhanced also by a factor of 2 compared to classic FMCW waveforms. The double staircase waveform with unequal slopes shows better results in terms of range and velocity resolutions compared to single staircase waveform. MATLAB simulation are done for a radar at 77 GHz and a bandwidth of 2 GHz.
