Spatial Resolution Enhancement for Non-Oversampled Data
Weidong Hu, Yuming Bai, Xin Lv · 2024
When the illuminations of spatial terahertz remote sensing toward the ground do not overlap, this situation is named non-oversampling. In such situations, the interpolation algorithm and super-resolution reconstruction algorithm can be used to enhance the spatial resolution of remote sensing images. In addition, utilizing the characteristics of multi-frequency observation, the method of multi-frequency image fusion can be used to improve the spatial resolution of low-frequency observation images.
