摘要
干涉合成孔径雷达技术作为一种遥感手段可以快速准确地获得地面三维信息。文中回顾了干涉合成孔径雷达近年来的一些重要研究成果,分析信号处理中配准、干涉、去平地、相位图降噪、相位展开、数字高程模型生成与校正的制约因素,分析运动补偿的原理和效果。对今后的研究热点和研究方向作一展望。
Interferometric Synthetic Aperture Radar (SAR) can get ground 3-D information quickly and accurately as a method of remote sensing.Some important research results on InSAR in recent years are reviewed.In InSAR signal processing,the factors in coregistration,interferometry,noise reduction, phase unwrapping,DEM generation and revision are analyzed.The theory and effect of motion compensation are analyzed.The future research points and direction are predicted.
