| Abstract: | Regarding the fact that ambiguous high resolution range profiles of stepped frequency radar is cycle extension, a new method to achieve unambiguous range profiles equivalent to mixing process is proposed, and the range of local mixing frequency is presented. Finally, the validity of this method is verified by simulation. |
