Book ChapterDOI
Imaging Through the Atmosphere
TL;DR: In this paper, the roles of atmospheric scatter, absorption, and turbulence are discussed and quantified, and properties of the imaging system in the extent of the atmospheric image degradation are also considered.
Proceedings ArticleDOI
Influence of severe vibrations on the visual perception of video sequences
TL;DR: In this article, the authors investigated the relative effects of two types of degradations on the ability of observers to recognize targets in a vibrating video sequence and determined the required precision of the deblurring and registration processes.
Proceedings ArticleDOI
Atmospheric effects on target acquisition
TL;DR: In this article, a brief overview and discussion of atmospheric effects on target acquisition in the IR is given, where the effects of the turbulent medium over long/short exposures are image blur and wavefront tilts that cause spatio-temporal image shifts, which limits the frequency of line pairs that can be resolved in the target's image and thus affects the ability to acquire targets.
Proceedings ArticleDOI
Imaging Through The Atmosphere For Airborne Reconnaissance
TL;DR: Turbulence, atmospheric background, and aerosol forward scattering MTFs are presented and analyzed with regard to both low elevation rpv and high elevation reconnaissance applications as mentioned in this paper, which can aid in sensor selection for system design from the standpoints of both wavelength selection and sensor resolution.
Proceedings ArticleDOI
Motion considerations for airborne reconnaissance of a target over hostile territory
TL;DR: The effects of this kind of motion are considered for two important areas, image quality and target acquisition and comparison between effects of linear and acceleration motion is presented.
