novel Frequency Modulated Continuous Wave (FMCW) is proposed in this paper. This waveform is composed of four continuous segments: one fast up-ramp followed by one slow down-ramp, a flat frequency and then a fast down-ramp. Two different slopes are used. For a single target, enhancement of range and velocity resolutions have been observed with respect to triangular waveform. Furthermore, challenges in multi-target detection caused by ghost and missing targets have been addressed in this paper using new algorithm. Depending on the ratio of the ramp-down slopes, the algorithm can separate the targets, identify the missing targets and remove the ghost targets.
