【摘要】 在遥感技术广泛应用的今天,合成孔径雷达(SAR)因其具有全天时、全天候成像能力及对地物有一定穿透力等独特的特点,已成为地学研究的一个重要手段。概述了合成孔径雷达技术的发展状况,对合成孔径雷达成像机理及特征做了简要介绍,同时对新兴起的合成孔径雷达干涉测量(INSAR)技术也做了简单描述,并就SAR在地质和地震研究中的应用进行了举例说明,充分肯定了合成孔径雷达技术在地质和地震研究中的重要作用。更多还原

【Abstract】 Remote sensing technique is widely used, and synthetic aperture radar (SAR) technique has become a very important means to earth science research for its ability to acquire images under all weather conditions and at all time as well as the particular penetration capabilities of microwave. This article focuses on summarizing the development of SAR technique, introducing the imaging mechanism and characteristics, describing the SAR technique briefly, and taking the examples to illuminate the application of SAR to geologic and seismic research. At last, the important functions of SAR are well confirmed.更多还原
