摘要
针对频率步进雷达中存在的高分辨距离像模糊现象,通过分析其本质原因——周期延拓引起循环移位,提出了一种等效混频解距离像模糊的新方法,并给出了等效混频本振频率的选择范围。通过仿真实验验证了该方法的有效性。
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.
