摘　　要：干涉合成孔径雷达利用同一目标区域2次成像的复图像间存在的干涉相位以及已知的测量参数提取目标区域的高程信息,其具备大范围、全天候、高精度的三维测绘能力。对合成孔径雷达干涉成像的原理进行了分析,提出了一种对合成孔径雷达干涉成像的有效干扰方法,仿真了正弦调频干扰对合成孔径雷达干涉成像的效果。The interference synthetic aperture radar uses the interference phase existing in the complex images imaged twice in the same target area and known measurement parameters to extract the elevation information of target area.It has the three-dimensional mapping capability of large-scale,all-weather and high-precision.This paper analyzes the inerference imaging principle of synthetic aperture radar,proposes an effective method to jam the inerference imaging for synthetic aperture radar,simulates the effect of sinusoidal frequency modulation jamming on inerferometric imaging of synthetic aperture radar.
