【摘要】 针对环境减灾二号A/B卫星环境评估、灾害监测、灾后恢复重建的需求，文章设计了一种单台地面分辨率优于16 m、对地幅宽大于200 km、5谱段推扫成像的空间遥感相机。该相机具有超大视场和轻小型等特点。经在轨验证，16 m相机各项指标满足设计要求，图像清晰、层次分明，在各类应用领域发挥了较大效能，可为农业、水土、森林资源普查及灾害、生态监测等提供参考。更多还原

【Abstract】 In view of the need of HJ-2 A/B satellites environmental assessment, disaster monitoring, and post-disaster reconstruction, this paper designs a space remote sensing camera which is used to obtain 5-band multispectral images with a ground sampling distance(GSD) of 16 m and swath 200 km. The camera has outstanding features such as a large field of view, a light and small size. After on-orbit verification, the indicators of the 16 m camera meet the design requirement, images are clearly and gradations are distinct, and it has played a great role in various application fields. It can provide reference for the census of agriculture, soil and water, forest resources, disasters, and ecological monitoring.更多还原
