Paper Abstract

In the imaging process of staring infrared Focal Plane Array (FPA), spatial-sampling frequency is determined by the physical size and spatial distance ofthe detecting unit. While the spatial frequency ofthe detected scene is always more than half of the sampling frequency of staring infrared Focal Plane Arrays, thus under-sampling happened, and the quality and utility of the image will be seriously degraded by aliasing. For the reduction of this effect, many scholars carried out a lot of theoretical analyses and bring forward some techniques. In this paper, theoretical analyses of forerunners are concluded, an integrated novel theoretical analysis on the reduction of aliasing is put forward, and the expectation of image reconstruction through uncontrolled micro-shift is discussed.
