卫星图像的空间分辨率是衡量卫星遥感能力的一项主要指标,也是衡量一个国家航天遥感水平的重要标志,追求更高的分辨率已成为各国卫星的发展目标。超分辨率技术在可见光遥感和红外遥感领域的实际应用,将会提高卫星的空间分辨率,也可以在保持卫星分辨率的条件下,缩小光学仪器的焦距,使卫星相机小型化,减小其体积和重量。本文从遥感应用的角度出发,讨论了超分辨率技术研究对我国遥感卫星提高分辨率的现实意义,简单说明了超分辨率的概念,论述了卫星遥感超分辨率研究的技术理论和和应用的国内外现状,重点突出了卫星采样模式的研究,提出了国内该项技术研究目前存在的不足和发展趋势。
The spatial resolution of satellite imagery is a major index to measure satellite remote sensing capability and an important indicator to measure the remote sensing level of a country. Pursuing higher resolution has become the development goal of satellites in various countries. The practical application of super-resolution technology in the field of visible light remote sensing and infrared remote sensing will increase the spatial resolution of the satellite and may also reduce the focal length of the optical instrument while keeping the resolution of the satellite so that the satellite camera may be miniaturized and reduced in size Volume and weight. Based on the application of remote sensing, this paper discusses the practical significance of super-resolution technology to improve the resolution of remote sensing satellites in our country, briefly explains the concept of super-resolution, and discusses the technical theory and application of super-resolution satellite remote sensing The status quo at home and abroad, with emphasis on the study of satellite sampling mode, put forward the current domestic technology research deficiencies and trends.
