Abstract
Recognition and identification ranges for targets in backgrounds are determined by the combined signatures of both target and background. In order to improve our understanding of the temporal behavior of cluttered backgrounds at infrared (IR) wavelengths in varying meteorological conditions, a series of experiments are described to model the observed IR imagery using the basic meteorological parameters recorded by a synoptic weather station. The acquired imagery covers a period of 44 hours. A simple multi-linear regression model using the basic meteorological data as input adequately describes the observations. Generally, only one to four weather parameters are required to model the observed apparent temperatures.
