摘　　要：从几何定量与辐射定量两个维度对我国陆地卫星技术发展进行总结与展望。近年我国陆地卫星的空间分辨率、几何定位精度等几何定量能力大幅提高,图像辐射质量明显提升,推动了我国卫星图像在行业的广泛应用。随着空间基础设施等规划逐步落地实施,将进一步补充激光、超光谱、多角度偏振成像等多种遥感探测手段,具备亚纳米级地物光谱与地表空间垂直结构的精确探测能力,提升图像辐射定标与光谱定标精度,促进我国陆地定量遥感卫星技术与应用发展。Development of China land satellite technology is reviewed in aspects of geometric and radiation quantification.Geometric quantification performances such as space resolution and geolocation have been improved significantly in recent years,and image radiation quality has been promoted obviously too,which accelerate the application of China satellite images in industries.With further implementation of China space infrastructure plan,additional remote sensing methods can be adopted such as laser,hyperspectral,multi-angle polarization imaging,and both sub-nanometer spectral resolution and vertical structure detection of land surface features can be achieved,and calibration accuracy of radiation and spectrum can be further improved,which will promote the development of China land quantitative remote sensing satellite technology and application.
