摘要
本文介绍了雷达解译研究的发展现状，通过对雷达影像和高光谱影像解译能力的分析研究，提出利用雷达影像和高光谱影像进行联合解译的技术思想；利用SIFT算法实现了雷达影像与高光谱影像的快速配准，基于地物光谱和空间特性研究了雷达影像与高光谱影像的联合分析和解译方法；通过试验验证，给出了试验结果。
The paper introduces the development of SAR image interpretation. A technical method of joint interpretation u- sing SAR and hyperspeetral image is given after analyzing the image interpretation capability. SIFT algorithm is used to realize the fast registration between SAR and hyperspeetral image. Studies on the joint analysis and interpretation method of SAR and hyper- spectral image are conducted based on the spectral and spatial characteristic of ground features. The joint interpretation experi- ments are carried out and the results are presented.
