超分辨率概念提供了超越经典极限的分辨率潜力。这一伟大的承诺尚未普遍实现。研究了超分辨率概念在合成孔径雷达中的潜在应用。讨论了超分辨率理论的分析基础。该概念在合成孔径雷达中的应用作为算子反演问题进行了研究。一般来说，算子逆问题是不适定的。然而，研究表明，正是相关算子的特征值谱的特定形式阻碍了合成孔径雷达图像的任何显着的分辨率增强。提出了图像超分辨率处理的判断标准。
Super-resolution concepts offer the potential of resolution beyond the classical limit. This great promise has not generally been realised. The potential application of super-resolution concepts to synthetic aperture radar is investigated. The analytical basis for super-resolution theory is discussed. The application of the concept to synthetic aperture radar is investigated as an operator inversion problem. Generally, the operator inversion problem is ill posed. However, it is shown that it is the particular form of the eigenvalue spectrum of the associated operator that precludes any significant resolution enhancement of synthetic aperture radar images. A criterion for judging super-resolution processing of an image is presented.
