高分三号卫星SAR工作模式与载荷设计
Design of Working Modes and Payload of SAR for GF-3 Satellite
摘要
Abstract
Considering the different requirements from multiple users,SAR payload of GF-3 sate-llite has the characteristics of high resolution,large observing swath,multiple polarization,mul-tiple working mode and high image quality,which bring great challenges to the design of SAR payload.The paper describes the SAR payload for the GF-3 satellite.Based on the requirement analysis,the overall realization scheme is determined and the working mode design is given.Fur-thermore,the design of SAR payload is described.Using a deployable planar active phased array antenna and the configurable electronics subsystem,the SAR payload has the abilities to obtain high-quality images and meet the requirements of mission.关键词
