摘　　要：提出利用光纤延迟线对宽带成像雷达进行转发式干扰的方法,论述光纤延迟线的结构和原理,以及宽带成像雷达的工作原理,并对宽带成像雷达转发式干扰进行仿真。通过分析得到,利用光纤延迟线对雷达信号进行延时和移频,可以有效地对宽带成像雷达进行干扰。Optical fiber delay line could be used to repeat signal of radar for jamming wide band imaging radar. The principles and structure of optical fiber delay line and imaging radar are analyzed. A simulation of repeater jamming on countering imaging radar is presented. The results show that wide band imaging radar can be jammed effectively in the way of time delay and frequency shift of radar signal with fiber delay line.
