本文概述了 GMES Sentinel-1 系统的特性，包括 SAR 成像模式及其关键性能参数，以及相关姿态和轨道控制模式（即横滚转向模式和零多普勒转向模式）的具体情况。此外，还讨论了 Sentinel-1 SAR 干涉测量 (InSAR) 功能。此外，本文还概述了计划中的 Sentinel-1 调试阶段与在轨 SAR 系统校准和端到端性能验证相关的活动。
The paper provides an overview of the GMES Sentinel-1 system characteristics including the SAR imaging modes and their key performance parameters as well as the specifics of related attitude and orbit control modes (i.e. roll steering mode and zero-Doppler steering mode). In addition, the Sentinel-1 SAR interferometry (InSAR) capabilities are discussed. Furthermore, the paper outlines the planned Sentinel-1 commissioning phase activities related to the in-orbit SAR system calibration and end-to-end performance verification.
