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。In view of the need of HJ-2A/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 16m and swath 200km.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 16m 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.
