- A pushbroom sensor consists of a line of sensors arranged perpendicular to the flight direction of the spacecraft. The earth's surface is imaged as the spacecraft flies forward. Supermode sampling using a pair of linear arrays in quincunx arrangement has been implemented on the SPOT5 earth observation satellite. In this paper, we propose a 45-degree tilting-mode sampling model with a square grid, whose sampling density achieves 2 times that of standard sampling, and then apply the estimated MTF of the real tilting-mode imaging system to ORC-based image restoration thanks to the anisotropic spectral support of 45-degree tilting-mode sampled images. Experimental results on simulated and real images validate the performance of the proposed method.
