航天飞机成象雷达3号及X波段合成孔径雷达(SIR-C/X-SAR)计划是一项包括中国在内有13个国家合作进行的大型雷达对地观测研究计划。SIR-C/X-SAR具有L、C、X3个波段及L、C波段HH,HV,VH,VV极化,X波段VV极化同时成象的能力,可获得全极化及干涉雷达数据,是本世纪内最先进的航天成象雷达系统。该文系统介绍了SIR-C/X-SAR中国项目开展以来取得的研究成果。重点阐述了中国雷达试验区及与SIR-C/X-SAR成象飞行同步开展的航天-航空-地面立体同步观测试验和对干沙的穿透性试验,以及在相关领域和不同地区的应用,包括昆仑山火山群的发现,广东肇庆植被覆盖区地质体的识别,明、隋两代长城的探测与极化响应分析,海洋及城市特征研究。

Shuttle Imaging Radar C and X-band Synthetic Aperture Radar mission(SIR-C/X-SAR) is an international cooperation program in radar for Earth observation There are 13 countries including China participated in this program SIR-C/X-SAR has three bands-L,C,X,polarimetry and interferometry imaging capability,the L and C band have polarization mode of HH,HV,VH,VV,and X band is only with VV polarization mode This paper introduces the China SIR-C/X-SAR program,its progress and achievements since its begining at six years ago While the shuttle flow over China,the Chinese scientists carried out the real time experiments including the spaceborne-airborne-ground data collection and sand layer penetration experiment Volcanos up to 5600m at sea level is discovered by SIR-C/X-SAR in Kunlun Mountains The lithological and structural features underneath vegetation cover is detected A segment of Great Wall in a desert region of the Ming and Sui dynasty has been identified,even part of the wall buried by Sand The prelimenary results of oceangraphy and urban study is also introduced and the interferometry technology for generating DEM is presented.
