摘要(Abstract)：

针对我国一些多云、多雨地区光学影像获取困难,且国内机载InSAR系统获取DEM精度普遍较低的问题,该文以国产机载微型InSAR系统为依托,首先,对InSAR原理和DEM获取流程进行了分析,着重对运动补偿和基线估计方法进行了归纳分析;其次,使用实验数据对国产机载微型InSAR系统的高程精度进行了验证分析,检查点高程中误差为0.44m,结果表明使用国产机载微型InSAR系统可以获取高精度DEM数据,满足我国测量规范对于丘陵地区1∶5 000成图比例尺地形图的要求;最后,为了进一步提高国产微型InSAR系统的测量精度,对控制点位置、定标器、DEM局部编辑等方面提出了建议。
