摘要 随着遥感图像分辨率需求的不断提高以及遥感卫星朝着小型化方向发展,超分辨率技术越来越受到重视。频谱编码超分辨率技术是近年来出现的新的超分辨率方法。它较传统的超分辨率方法而言,结构简单,且能实现较高的超分辨率倍数。频谱编码板是频谱编码超分辨率技术的关键部件。根据傅里叶光学理论展开分析,对频谱编码板进行了简单的设计,并对一维和二维频谱编码超分辨率方法进行仿真。根据仿真结果对影响因素进行了分析,并简要的提出了解决方案。 Geometric superresolution is an important technology to improve resolution of remote sensing. Code division multiplexing is a new method of the technology. This method does not involve additional mechanical elements, such as those used for microscans. Fixing the code-division-multiplexing board using the Fourier optics is discussed and the 1D and 2D images are simulated. Then, the influnceing factors on the result of simulations are analyzed, and the solutions are given briefly.
