Applications of high-resolution space-borne SAR in mining disaster monitoring
Abstract：SAR（synthetic aperture radar） has more advantages of day/night capabilities,all weather capabilities,and wind/clouds/rain/snow/vegetation penetration capabilities and so on.It is the most important advance of space remote sensing and earth observation technology in recent 20 years.In the 21st century,a series of the high-resolution space-borne SAR successful operation symbolize the radar remote sensing and earth observation going into a new era.In this paper,the superiorities of the high-resolution SAR data and the application bottlenecks of the middle or low-resolution SAR data due to low-resolution are summarized.An overview of the current high-resolution sensors feature of SAR satellites in orbit,for example COSMO-Sky Med satellites of Italian,the Radarsat-2 satellite of Canada and the Terra SAR-X satellite of German,is described.The studies in the fields of geological disasters deformation monitoring by using high-resolution SAR backscatter information and phase information at home and abroad are referred,especially geological disasters monitoring in mining areas.Finally,a prospect of high-resolution SAR technology applications of mining subsidence and geological disasters monitoring is expected.
