南京市活动断层卫星遥感图像的研究

采用对地表具有一定穿透能力的合成孔径雷达数据(ERS-2SAR)和光谱信息丰富的常规光学遥感数据(Landsat-7ETM)作为主要数据源,综合利用不同传感器不同成像方式的成像优势,进行图像恢复处理、图像增强处理与信息融合来突出南京目标区隐伏线性构造的影像特征。然后通过分析建立活动断层的影像解译标志,共解译出工作区内4条主要活动断层,并对其影像特征与活动性进行分析。本研究采用了微波遥感与光学遥感相结合的方法来研究被第四纪覆盖的隐伏构造特征,克服了单一遥感手段的不足,获得了较为理想的效果。

The Research on Remote Sensing Images of Nanjing Active Falts

Adopting the synthetic aperture radar data(ERS-2 SAR)which have the certain penetration ability to the earth's surface and the routine optics remote sense data(Landsat-7 ETM)which have rich spectrum information to be the main data source,carrying out the image recovery,image strengthen and the information amalgamation processing to stress the image characteristics of concealed linearity structure in Nanjing target area by utilizing synthetically the imaging advantage of different sensors and different imaging ways.Then building the image interpretation and analysis signs of active faults by analyzing,in the work area four main active faults in total were interpreted,and their image characteristics and activity were analyzed.This research adopts the associative method of the microwave and the optics remote sensing to study the characteristics of concealed structure covered by Anthropogene,therefore,having overcome the deficiency of unitary remote sensing means and gained comparatively ideal effect..
