中文摘要：

本技术框架的目标是准确仿真国土应用关心的卫星高分辨率相机成像过程中的辐射和几何质量的下降情况，从应用的角度建立评价高分辨率卫星相机在国土资源领域应用潜力的技术框架，并以CBERS-02B高分辨率相机在轨成像模拟为例进行了原理验证，同时对今后以国土资源应用评价为目标的高分辨率相机在轨成像模拟改进方案提出了建议。

英文摘要：

In this paper, the authors＇ simulation technical framework focuses on the simulation of degeneration of the radiometric and geometric qualities of the images which constitute the fundamental criteria in land and resources management application. The authors have given a detailed description of the framework for digital simulation of the high resolution optical sensor and verified it with CBERS -02B satellite equipped with a high resolution optical sensor of 2.4m ground sample resolution. A potentially improved simulation framework is also put forward.
