An equalizer which makes use of the sparse structure is expected to have better performance than one which does not. We compare the performance of the two types of equalizers by

In this paper, we propose a novel Successive Multiple Frequency Continuous Wave (S-MFCW) modulation scheme to address these challenges. The S-MFCW signal model is formulated and the impact of noise is analyzed, leading to a very short dwell time and narrow signal bandwidth with excellent range and speed accuracy. From the numerical simulation of an automotive radar example, we show that S-MFCW achieves comparable range and speed performance, but orders of magnitude lower requirements on dwell time and bandwidth compared to the commonly used FMCW radar.
