基于HJ-1C卫星数据的活动断层提取研究

Studing Of Interpretation From The Active Fault Based On The HJ-1C Data

在活动断层遥感解译中,SAR数据能发挥重要作用,SAR图像虽不直观,但对植被、浅层土壤具有较好的穿透能力,并且SAR可以在全天候条件下成像。本文以国产HJ-1C卫星SAR数据为例,通过滤波、纹理分析、融合等图像处理方法增强阳原地区断裂信息,提取了阳原盆地南北两条边界断裂,即六棱山北麓断裂和阳原盆地北缘断裂。在此基础上,对阳原地区活动断裂进行了综合解译。相关工作表明,HJ-1C数据具有实用性,同时也说明HJ-1C在断层解译方面具有一定的潜能。

Most of the interpretation studies of fault is based on the optical image of remote sensing,and there are little people to use SAR data to extract the fault information,because the SAR image is intensity map,can’t clearly reflect the intuitive characteristics of fault.However,on the other hand,radar not only has a good penetrability on vegetation,shallow soil,but also isn’t affected by the bad weather,which can provide detailed ground mapping data and images in allweather conditions.So,this paper used HJ-1C SAR data by filtering,texture analysis of image processing method to analyse and interpreted Yangyuan area fault information,obtaining more intuitive and clear fault information based on construction of process,which proved that the SAR image has great potential in the fault solution translation,and the HJ-1C has good feasibility and practicability in fault interpretation.
