Chirp-SF signal is a new kind of high range of resolution signal. This paper firstly points out that the traditional signal processing methods will cause “ghost images” when there is more than one scatter in a distance unit. Then a new method which including interfacing each sub-pulse in the Timeline and frequency shifting to Constitute a FM signal is proposed. We can solve this problem and have a high range resolution by execute the pulse compression on the synthetic signal. In the end, the simulation result is shown to prove the correction of the Algorithm.
