摘 要: 介绍了TerraSAR-X这一现代高分辨率雷达卫星的有关情况,主要涉及成像模式、产品种类、产品格式和应用领域等方面。TerraSAR-X卫星是德国研制的新型雷达卫星,于2007年6月15日发射成功。该卫星携带一颗高频率的X波段合成孔径雷达(synthetic aperture radar, SAR)传感器,能够以3种不同模式成像,并且具备多种极化方式。聚束式、条带式和宽扫式3种成像模式,不但能获取高分辨率的影像信息,还能全天时、全天候地覆盖用户要求的任一成像区域。极化方式包括单极化、双极化和多极化。TerraSAR-X是目前集科研和商业应用于一体的先进的SAR卫星之一。
关 键 词: 摄影测量与遥感技术;TerraSAR-X;成像模式;高分辨率;极化

Abstract: This paper describes the basic information of TerraSAR-X satellite, including imaging modes, products, structure and application. TerraSAR-X is a new German radar satellite that has been launched on June 15, 2007. It carries a high frequency X-band SAR sensor which can be operated in three different modes and have multiple polarization modes. The spotlight, stripmap and scanSAR modes provide high resolution images for detailed analysis as well as wide swath data whenever a larger coverage is required. The polarization modes include single, dual and multi polarization modes. TerraSAR-X is an operational SAR system for scientific and commercial applications.
Key words: photogrammetry and remote sensing; TerraSAR-X; imaging modes; high resolution; polarization
