摘　　要：从理论上分析了弹射式干扰对SAR图像干涉相位的影响,仿真了弹射式干扰前后INSAR成像处理过程,通过INSAR成像过程中相位图质量、相位频谱分布的评价阐述了弹射式干扰对INSAR成像的影响,并得出弹射式干扰可对单航过测高INSAR形成有效的欺骗式干扰效果的结论。The effect of rebound jamming on the interferometirc phase is analyzed in theory firstly. Then the INSAR images process is simulated. The effect of rebound jamming on the INSAR imaging is analyzed by stimulating the phase quality and the spectnun distribution. It is concluded that rebound jamming is a kind of effective deceiving jamming on INSAR altimetry.
