高分三号卫星总体设计验证
System Design Verification of GF-3 Satellite
摘要
Abstract
GF-3 satellite is the only microwave imaging satellite of the NHREOS (national high resolution earth observation system), as well as the first C-band multipolarity SAR (synthetic aperture radar)satellite with 1 m spatial revolution in China.The satellite has the requirement of high quantitative application index,as well as some technical characteristics and difficulties such as large mass and size of radar antenna, high requirement of thermal control,high power and complex structure at the same time.So in the paper,the system design characteristics and design verification methods are introduced such as high image quantification and high scalability. The high image quality and quantification application are achieved by using system modeling, simulation analysis, ground test and on-orbit test, which makes the satellite have on-orbit expansion ability.The verification methods adopted in design and development process of GF-3 satellite can be used to system design of other SAR satellites.关键词
