| 中文摘要: |
| 成像雷达(SAR)遥感以其独有的全天时、全天候观测能力和对地表的穿透性及形态探测能力,特别是现在新型成像雷达遥感技术的发展,使之在地质学应用中比光学遥感更具优势.文章结合SAR应用技术的发展过程,即由单波段单极化到多波段多极化,再发展到现在极化测量和干涉测量阶段,综述了成像雷达遥感在地学中的应用,特别对新型成像雷达技术(极化雷达、差分干涉雷达)在岩性分类、探测地震区域形变的地学应用作了实例介绍. |
| 英文摘要: |
| SAR remote-sensing instruments with the capabilities of all weather and all day/night, penetration, and terrain detection, especially the development of new imaging radar technologies, i.e. polarimetric SAR (PolSAR) and interferometric SAR (INSAR), provide unique geological environmental information, quite different from and complementary to passive systems such as visible, infrared and passive microwave radiometers. SAR data provide unique information about geology, such as lineament features, fault zone, stratum outcrop,and volcanic formation, as well as critical data for geological hazards and mineral resource assessments. PolSAR and INSAR data are crucial for accurate lithology classification, measuring terrain change, delineation of geology mapping.The development of geological application of radar remote sensing technology is reviewed in this paper, that is, from single-band, single polarization to multi-band, multi-polarization, then to PolSAR and INSAR. |
