2020年5月中国东部哨兵S1A-IW原始遥感影像数据集

哨兵1包括哨兵-1A和哨兵-1B两颗卫星。这两颗卫星是处于同一轨道平面的极轨卫星，分别于2014年4月3日和2016年4月25日成功发射。
这两颗卫星搭载C波段合成孔径雷达，具有4种成像模式，可为陆地和海洋服务提供全天时、全天候的雷达图像，提供一系列运营服务，包括北极海冰，日常海冰测绘，海洋环境监视监测科研，监测地面运动风险，森林制图，水和土壤管理和测绘，以支持人道主义援助和危机情况
SAR系统可以通过多种方式获得图像，如单通道或双通道模式（如HH、HH / HV或VV / VH)、干涉 (单轨或多轨)模式、极化模式(HH,HV,VH,VV)、干涉及极化组合采集模式，不同的获取模式对应了不同的处理方法

Sentinel-1 consists of two satellites: Sentinel-1A and Sentinel-1B. Both are polar-orbiting satellites in the same orbital plane, and were successfully launched on April 3, 2014 and April 25, 2016 respectively.
Both satellites are equipped with C-band synthetic aperture radar (SAR) systems, featuring four imaging modes. They provide all-day, all-weather radar imagery for land and ocean applications, and support a range of operational services including Arctic sea ice monitoring, routine sea ice mapping, marine environmental surveillance and research, ground movement risk monitoring, forest mapping, water and soil management and surveying, to support humanitarian assistance and crisis response.
SAR systems can acquire images via multiple acquisition modes, such as single-channel or dual-channel configurations (e.g., HH, HH/HV or VV/VH), interferometric (single-pass or multi-pass) modes, polarimetric modes (HH, HV, VH, VV), and combined interferometric and polarimetric acquisition modes. Different acquisition modes correspond to distinct image processing methods.
