Abstract

The objective of this work is to explore the consequences of using present-time-only data for infrared signature predictions on tracked vehicles, and to quantify the error that is introduced by this steady state analysis approach. The paper will focus on the effects of three independent variables; spectral reflectance, thermal capacitance and the time of day that the simulation takes place. The error analysis will be deconstructed to the basic elements of sensor prediction; thermal and radiance analysis. The study was conducted parametrically in order to capture a range of applicability for tracked vehicles. The outcome of the study is a set of guidelines, outlining the period of time necessary to rid a model of equilibrium error.
