| 摘 要： | 从卫星硬件设计与地面软件处理相结合的角度出发，建立了一套提高卫星图像空间分辨率的方法。对模拟靶标图像、一航景物图像、遥感图像分别进行了不同分辨率成像效果的计算机模拟。结果表明，所建立的卫星图像空间分辨率提高理论是正确的，使卫星图像空间分辨率提高2倍甚至更多在理论上是可行的。这一研究成果的实际应用，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。

| Abstract: | By the integrating satellite hardware's design with ground software's processing,the article presents a new theoretical method for improving the spatial resolution of satellite image.Computer simulations under different resolution levels are carried out on simulated target images,common scenery images and Remote Sensing images separately.The success results of experimental simulations show clearly the method for improving resolution we present is valid in theory,which also proved the theoretic feasibility to enhance the spatial resolution of satellite images up to twice,even N times,Obviously,practical applications of the research will enhance the spatial resolution of satellite images.In addition,it can also help shorten optical instruments' focus,decrease satellite camera's size and mass while remaining the same spatial resolution of satellite images. |
