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 ȁC;ghost imagesȁD; 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.
