摘　　要：动态范围是遥感器的一项重要性能指标,设计是否合理直接关系到卫星图像的层次、亮度和对比度,最终影响图像的品质。文章根据CCD相机的成像原理,结合中国已发射遥感卫星的在轨像质,对CCD相机动态范围的设计进行分析并提出一些建议。Dynamic range of remote sensor was an important factor, which decided the brightness and contrast of satellite images, and finally affected the image quality. The paper briefly intrtoduced the images analysis of launched satellite, the image theory of CCD canera, and gave some suggestion on how to design the dynamic range of CCD canera.
