Thermal Modeling of Battlefield Scene Components.

The work reported herein addresses the battlefield signature modeling part of the Army-Wide Signature Program, and in particular the ability to consider quantitatively the effect of battlefield environmental conditions on the performance of electro-optical surveillance and target acquisition devices. An initial capability was developed to estimate the ranges of temperatures that can occur over the diurnal cycle for specific terrain features and climatic conditions. The capability consisting of formulating a generalized terrain data base for the Federal Republic of Germany FRG, a representative climatic data base derived from measured weather data, and models for predicting time-dependent temperature histories for selected terrain surface conditions. The terrain and climatic data bases are presently interfaced with the temperature models individual models for terrain surface features and vegetation components by a matrix concept for selecting quantitative values for the model input parameters. A variety of model output products is presented for selected terrain features in the Fulda, FRG, area for winter and summer climatic conditions. A recommended plan for future research was formulated and is presented in the report.
