17032 合成孔径雷达(SAR)成像中通常默认大气折射率为1，即电磁(EM)波速率等于自由空间光速且忽略大气吸收特性， Generally, the refractive index of atmosphere is simply 1 by default in Synthetic Aperture Radar(SAR) imaging, that is, the ElectroMagnetic (EM) wave velocity is equal to the speed of light in free-space andthe atmospheric absorption is ignored.
17033 但实际存在的吸收会减弱入射功率，电磁波速率的变化会引起相位误差，从而影响图像重建。 However, the actual absorption may weaken the incident power andvariations in the speed of EM waves may cause phase error, thus affecting image reconstruction.
17034 该文定量分析电磁波速率波动和大气吸收对雷达图像的影响，理论推导得出大气吸收会导致振幅误差，表现为散射点在图像中的重建幅度误差； In this paper, the influence of wave velocity fluctuation and atmospheric absorption in SAR imagery is analyzed quantitatively. It is theoretically deduced that the atmospheric absorption will lead to amplitude error, which isshown as strength error of the scatterer in the reconstructed image;
