Abstract
In this paper the effects of scattering, with four atmospheric fog aerosols models, on the overall point spread function (PSF) of an imaging system are investigated. The PSF and radiometric calculations are then used to estimate the mean numbers of direct path and scattered photons detected by the imaging system in the visible and near infra-red (NIR) spectral bands of the electro-magnetic spectrum (EMS), for a horizontal near-ground imaging scenario. The image spectrum signal-to-noise ratio (SNR) is then used to estimate the noise effective spatial resolution of the imaging system which emphasizes the degrading effect of fog aerosol models on the spatial resolution of the imaging systems.
