干涉式合成孔径雷达干扰方法研究

干涉式合成孔径雷达（INSAR）三维成像技术是在合成孔径雷达（SAR）的基础上发展起来的，它可以获得高精度的数字高程模型（DEM），该模型得到了广泛的应用。针对IN—SAR干扰对比研究了常规噪声压制式干扰与弹射式干扰对INSAR成像处理的影响，并作了计算机仿真。结果表明，采用弹射式干扰不仅可行，而且可以有效地改变原地形的“指纹”特征，达到欺骗INSAR的目的，而常规噪声压制干扰则不适合用于对INSAR实施干扰。

Research on jamming to interferometric synthetic aperture radar

INSAR is developed on the basis of conventional SAR techniques, which can image three dimen- sion terrains and obtain digital elevation model （DEM）. DEM are widely used. The purpose of this work is to investigate the feasibility of INSAR interference and contrast the effects of conventional noise barrage jamming and rebound jamming to the imaging technique of INSAR. The result of computer simulation demonstrates that rebound jamming can change the finger mark of the original terrain to bamboozle the INSAR successfully while the conventional noise barrage jamming can not.
