2000年,Ekestorm 等[8]首先对截获的SAR信号进行相位和幅度调制形成了SAR 欺骗干扰信号,在SAR 成像结果中产生了虚假目标,这启发了后来者对SAR 欺骗干扰的思路。2002 年,胡东辉等[9]针对SAR 提出了散射波干扰这一种新的干扰思路,利用仿真手段证明了该方法生成的干扰图像所包含的地物信息比其他干扰方法生成的干扰图像...
层析合成孔径雷达(Tomographic Synthetic Aperture Radar, TomoSAR)在高程向合成孔径,利用多幅稍微不同视角下同一场景的二维图像建立起观测向量与高程向散射系数剖面的变换关系,可以得到高程向每个散射体点的位置和散射系数,真正解决了SAR叠掩问题[1]。 层析概念是由计算机断层成像技术(Computed Tomography)扩展而来。2000年...
How can you call when your mobile phone is showing no signal? Or if somebody in your party is unconscious and their�s is the only mobile, �how can you bypass the phone security to make that important call and potentially save their life? All this and more is explained simply and c...
