摘　　要：需要一个平台对探月卫星,探月图像传输和处理进行研究.嫦娥一号月球图像的传输与处理的仿真,结合了链路分析,采用MATLAB GUI和虚拟现实设计工具。由于图像在深空传输中,距离较远,信号会受到很大的衰减,传输质量会受到噪声干扰的严重影响。因此要对系统链路进行严格的预算分析,包括考虑地球大气产生的影响,以确保信号传输质量满足要求,另外还要通过适当算法提高图像的清晰度。这种仿真方法对探月图像传输的研究奠定了基础,并且对降低探月成本有一定的帮助。For the research on lunar satellite,lunar image transmission and processing,a platform is required.The lunar image transmission and processing of Chang＇e-1 are simulated in combination with the link budget by using MATLAB GUI and virtual reality design tool.Imaging signal has to pass a long distance during the deep space transmission,and suffers a tremendous attenuation.The image has got serious noise,thus making the picture blurry.Therefore,the link budget including the influence of the atmosphere should be taken very carefully,to make sure that the image quality is acceptable.On the other hand,some image processing algorithms are also considered.This simulation methodology has been an important foundation for lunar image transmission research,and all of these efforts would make for cutting down the Lunar Exploration cost.
