Abstract

Imaging radiometer sampling and integration period determination studies are contributed to by: a) performing an empirical study of the sampling rate´s effect on the spatial resolution of the resulting image, b) analyzing the effect of supplementing thermal noise on a numerical model expressing the influence of sampling and integration periods on the achievable spatial resolution, and c) discussing the optimal values for the sampling and integration periods on the basis of a scan simulation study
