摘　　要：针对空间光学高分辨率遥感器,既要实现轻小型化,又要获得高品质遥感图像的要求,文章提出一种空间光学遥感成像系统优化设计新方法;综合考虑成像链路各环节因素,采用全面的指标设计和合理的优化设计流程来改进空间光学遥感成像系统的总体指标和成像品质,并显著降低遥感器的研制难度。通过比较全链路优化设计方法和传统设计方法的仿真结果及其评价指标,验证了全链路优化设计方法可行性和优势。Space optical remote sensor of high spatial resolution need to meet the requirement of both light and small design and high imaging quality.In this paper,a trade-off method for space optical remote sensing imaging system is presented,which synthetically considers all factors in image chain.This method is used to enhance image quality by comprehensive index design and rational design method.Additionally,this method could reduce the difficulty of manufacture.The contrast between the trade-offs method and traditional method validates the feasibility and predominance of the trade-offs method.
