摘要
相干干扰方法是对合成孔径雷达的一种有效干扰手段。针对合成孔径雷达相干干扰在距离向上只能压制部分区域,在方位向上干扰区域与无干扰区域界线清晰的现象,在阐述虚假目标产生原理的基础上,从虚假目标成像位置、虚假目标成像质量两个方面,分析了干扰机布站位置对合成孔径雷达相干干扰效果的影响,找出了上述现象产生的原因并提出组网干扰策略。
The coherent jamming is an effective means to Synthetic Aperture Radar(SAR).SAR coherent jamming can only suppress part of the region in the distance direction,interference and noninterference area boundaries clear phenomenon in the azimuth direction,the effect of jammer position on SAR coherent jamming is analyzed from the imaging position and image quality of false target on the basis of principle of the false target,and the reason of the above phenomenon is find out and the network policy is proposed.
