合成孔径雷达干涉测量已广泛应用于高精度数字高程模型的生产,本文在深入分析合成孔径雷达干涉测量原理的基础上,基于相关InSAR开放源代码软件,在Linux系统下,初步构建了一个干涉测量处理软件平台,利用欧空局提供的Envisat卫星数据,成功提取了国外某地区高精度的数字高程模型。通过与高精度SRTM数据的对比,发现实验所获取的DEM更平滑,分辨率更高,证明了本文所构建的干涉处理软件平台可靠有效。
Synthetic aperture radar interferometry has been widely used in the production of high precision digital elevation model. Based on the in-depth analysis of the principle of synthetic aperture radar interferometry, based on the relevant InSAR open source software, under the Linux system, an interferometric measurement Processing software platform, using the ESA satellite data provided by ESA, successfully extracted a high-precision digital elevation model in a certain area abroad. Compared with the high-precision SRTM data, we found that the DEM acquired by the experiment is smoother and the resolution is higher. It proves that the software platform of the interference processing constructed in this paper is reliable and effective.
