| 摘 要： | 本文描述了机载双天线合成孔径雷达干涉测量数据生成数字高程模型(Digital Elevation Model,DEM)技术,针对机载双天线InSAR数据自动生成DEM的数据处理流程进行试验,主要包括:复图像配准、干涉条纹图滤波、相位解缠、相高转换。本文基于VC++开发了机载InSAR干涉处理原型系统,利用分辨率为2m×2m的机载双天线X波段InSAR数据进行了干涉处理实验,并将生成的DEM和实测的控制点数据进行了对比分析。试验结果证明基于机载双天线InSAR数据生成DEM技术可满足1:50000的精度要求。

| Abstract: | The paper describes how DEMs are obtained using the airborne dual-antenna Synthetic Aperture Radar Interferometry(InSAR) data,and proposes the data processing flow,including complex image registration,interferogram filtering,phase unwrapping,parameter calibration,height derivation and geo-coding.The airborne InSAR processing system has been exploited based on the VC++.The airborne dual-antenna X-band InSAR data is used as the Experimental data,and the processing results are obtained and analyzed.Finally,the generated DEM and the measured ground control points are analyzed contrastively.It meet the requirements of 1:50000’s DEM accuracy.The airborne InSAR system provides the new technique?for large or difficult area topographic mapping. |
