in fm-cw radar i use saw tooth ans sweep of freq when i sweep frequency the reflected signal with the same frequency but shifted with time (signal time) which i can get beat frequency but when tx signal restart sweeping and reflected signal still in the previous sweep the opfreq=band width-fb until the reflected signal end its seep and catch the sweep of tx signal how can i over come that?

That sounds like a question for a signal processing forum, rather than for a forum about MATLAB and Simulink.

In general, for an FMCW radar, your modulation time is couple of times longer than the time corresponding to your maximum range, hence making sure that you have enough energy to detect the return.
