对成像雷达的间歇采样非均匀转发干扰方法
|
摘要
间歇采样转发干扰是针对宽带成像雷达的一种有效干扰方式。根据间歇采样转发干扰的基本原理,对宽带成像雷达,按照常规的均匀转发方式,能够在高分辨距离像结果中叠加一串位置均匀分布的虚假散射点。虚假散射点序列的均匀分布特点不利于干扰信号的伪装。针对此问题,以破坏虚假散射点序列均匀分布为目的,在常规间歇采样转发干扰方法基础上,提出间歇采样非均匀转发干扰方法,并分析其干扰效果。最后通过仿真实验验证了所提出的方法能提高对宽带成像雷达的干扰效果。
ISRJ(interrupted-sampling repeater jamming) is an effective method to wideband imaging radar.According to the basic principle of ISRJ,when the jamming with conventional uniformly repeater is applied to wideband imaging radar,a string of uniformly spaced artificial scatters are overlain on the high resolution range profile.The artificial scatters' characteristic of being uniformly spaced goes against with the camouflage of jamming signal.In order to solve this problem,based on the conventional ISRJ,a new jamming method using interrupted-sampling un-uniformly repeater,in which the main purpose was broken the uniformly spaced of artificial scatters,was put forward,and the effect of the new jamming method was also analyzed.Finally,by means of simulation,it is found that the new jamming method can promote jamming effect to wideband imaging radar.
