摘要
为解决光学遥感在植被覆盖区地质构造信息难以识别提取的问题,利用具有一定穿透能力的L波段PALSAR双极化雷达数据对福建寿宁地区开展了研究。对双极化雷达图像进行了假彩色合成、滤波增强,针对HH极化通道将灰度图像变换成HSV彩色图像,突显了地质信息,并与该区ASTER多光谱影像进行了对比,分析了雷达影像优劣。结果表明PALSAR雷达构造解译结果与研究区的区域主要断裂方向基本一致,PALSAR雷达数据可以作为高效、准确的方法 ,在植被覆盖区开展遥感地质工作。
In order to solve the problems that the remote sensing technology facing in the geological structure information extraction of the vegetation-covered area,taking Fujian Shouning Area as a research area,we used L-band PALSAR dualpolarization radar data with certain penetrating power to do research.For detailed structural information,we performed the false color synthesis and filter to the data,and transformed the HH polarization channel into HSV color image.Finally,comparing with ASTER multi-spectral images in this area,we analyzed the advantages and disadvantages of PALSAR radar images.The results show that the interpretations of PALSAR radar structures are consistent with the main faults in the study area.The achievements of this investigation established the helpfulness of PALSAR data for geological structure analysis in the vegetation-covered area.
