目前,我国遥感技术应用中最普遍采用的是通过光学遥感获取影像,这种方法一般需要控制点才能获得高分辨率遥感影像,不可避免地限制了其应用范围。然而TerraSAR-X具有精确的传感器校正、高精度的卫星位置及对卫星姿态的低依赖性等特性,在无地面信息的情况下,仍然可以获得高精度的遥感影像。因此,研究利用TerraSAR-X数据作为地面控制信息对光学遥感影像进行地理定位具有突破性的意义和价值。本文介绍了近几年TerraSAR-X影像对光学遥感影像进行定位的现状和方法,阐述了其理论基础和优缺点,并试着分析了现阶段争论的焦点。

The most widespread application of remote sensing technology is to obtain images through the optical remote sensing current -ly, in which case generally require the ground control points in order to obtain high -resolution remote sensing images , which inevita-bly limits the scope of its application .However , TerraSAR-X has a precise sensor calibration, precision satellite position and attitude of the satellite low dependence and other characteristics , in the absence of information on the ground situation , it can still get high ac-curacy of remote sensing images .Therefore, the study of TerraSAR -X data as ground control information on optical remote sensing images geopositioning have some groundbreaking significance and value .This article describes the current status and methods of the optical remote sensing image positioning based on TerraSAR -X image in recent years , explains its theoretical basis and the pros and cons, and try to analyze the focus of debate at this stage .
