摘要 对于获取模型进行理论分析,导出一种有效的可以直接计算的方法.不需要迭代,不需要预条件处理,计算过程中主要采用快速傅里叶变换及小矩阵求逆,计算效率高.将该结果扩展应用到GCV法求相应的规整化参数,给出仿真结果. In this paper, we derive a fast super-resolution reconstruction algorithm. The new algorithm is noniterative, and it needs the FFI" algorithm and the inverse of little-size matrices. The method is extended to find the regularization parameter through the GCV algorithm.
