摘要
本文介绍了现有合成孔径雷达卫星数据源,阐述了星载雷达干涉数据处理流程和主要关键技术,对影像精匹配、大气改正、相位解缠等数据处理方法进行定性定量分析,利用公开的哨兵卫星雷达影像和精密轨道数据提取实验复杂山区高精度数字高程模型,并进行三维地形特征分析。结果表明,融合公开星载数据的雷达干涉技术可为规划设计研究提供大尺度的数字高程模型。
This paper introduces the existing spaceborne synthetic aperture radar(SAR)satellite data sources,expounds the radar interference data processing flow and the main key technologies,makes qualitative and quantitative analysis on image matching,atmospheric correction,phase unwrapping and other data processing methods,extracts the high-precision digital elevation model of the experimental complex mountainous area by using the free Sentinel-1 SAR images and precise orbit data,and carries out three-dimensional analysis.The results show that the radar interferometry based on open source data can provide large-scale DEM for planning and design.
