Multiple Frequency Continuous Wave (MFCW) is one of the efficient methods having both long range performance and range resolution. In this paper, the transmission sequences and signal processing to expand the observable maximum velocity and maximum range of MFCW are described. At first, we propose Hybrid Sequence MFCW in which frequency steps for the velocity estimation are added to the conventional MFCW to expand the observable maximum velocity. And then we also propose the signal processing using two initial frequencies to expand the observable maximum range. We show the initial experimental results on a general road. The results indicated that both proposed methods worked well on the field experiments.
