任务简介

RISAT-1B 是印度空间研究组织(ISRO)雷达成像卫星 RISAT-1 系列的第三颗卫星,采用有源 C 波段合成孔径雷达(SAR),具备全天候、昼夜 SAR 观测能力,可应用于农业、林业、土壤湿度、地质、海冰、海岸监测、目标识别、洪水监测以及军事侦察等领域。 RISAT-1 系列由 ISRO 研制、制造和集成。三轴稳定卫星平台采用六棱柱结构,围绕中心圆柱体建造。大部分卫星子系统和有效载荷集成在棱柱结构和中心圆柱体中。太阳能电池板及部分子系统安装在卫星的立方体部分。

RISAT-1B is the third in the series of radar imaging RISAT-1 satellites of ISRO using an active C-band SAR (Synthetic Aperture Radar), providing all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, in addition to military surveillance. The RISAT-1 series is developed, manufactured and integrated by ISRO. The 3-axis stabilized spacecraft bus consists of a hexagonal prism shape build around a central cylinder. Most of the spacecraft subsystems and the payload are integrated in the prism structure and the central cylinder. The solar panels and some subsystems are mounted on the cube-shaped section of the spacecraft.
