| 摘 要： | 基于某机载高分辨SAR系统的飞行试验,研究机载高分辨成像面临的问题以及补偿措施。由于INS/GPS数据难以满足精度要求,研究从回波数据中提取多普参数,进行运动补偿和视线位移补偿;剩余相位误差通过PGA进行补偿,从而得到0.3 m高分辨SAR图像的成像。

| Abstract: | Based on the High Resolution SAR system experiments. Some problem that influenced the quality of image was discussed. Since The INS did not meet the need of Error Compensation, Doppler parameters (fdc,fdr) was obtained by SAR Raw data to compensate the LOS error and phase error. The residual Error was compensated by PGA method. Then the high quality of SAR image was obtained. |

| Keywords: | Synthetic aperture radar(SAR) Motion compensation Displacement in LOS direction PGA |
