对预警雷达STAP的间歇采样转发干扰研究

Research into Intermittent Sampling Repeater Jamming to Early-warning Radar STAP

介绍了时空自适应处理(STAP)的应用背景和干扰方法,阐述了STAP技术的原理,建立了间歇采样转发干扰模型,对比分析了间歇采样转发干扰的效果。结果表明尽管STAP可以提取被强地物杂波淹没的目标,但采用间歇采样转发干扰可以影响STAP提取目标信息,干扰效果明显。

This paper introduces the application background and jamming method of space time a-daptive processing （STAP） , expatiates the theory of STAP technology, builds up the model of in-termittent sampling repeater jamming, contrasts and analyzes the effect of intermittent sampling re-peater jamming. Results show that although the target submerged by strong ground clutters can be abstracted by STAP technology, using the intermittent sampling repeater jamming can affect the target information abstraction by means of STAP,and the jamming effect is obviously.
