摘要
环境减灾-1A、1B卫星装载的宽覆盖多光谱CCD相机实现了地面像元分辨率优于30m、对地幅宽大于700km、4个谱段推扫成像。CCD相机自2008年9月8日首次开机成像后,不断获取地面可见光信息.图像清晰、层次分明,图像数据广泛应用于灾害监测与评估、灾后恢复重建等方面。文章就HJ-1A、1B卫星CCD相机的设计原理、技术难点、进步点及创新点等进行了总结。
The CCD camera on HJ-1A/1B satellites is used to obtain 4-band multispectral images with a ground sampling distance （GSD） of 30m and swath of 700km. Since the data generated by the camera were firstly sent back to the Earth on Sept. 8, 2008, the camera has worked well up to now, and large quantities of photos for disaster detection and environment protection have been sent back. In the paper, the design principle and the design result of the camera are introduced.
