The general purpose of this handbook is to provide Army design engineers, scientists, and analysts with a method to quantify obscuration factors for electro-optical EO and millimeter wave mmw systems. The specific purposes are 1 to provide data and methodology for Army design engineers to asses the effects of natural obscurants and battlefield-induces contaminants on EO and mmw systems, 2 to provide the analytical community with information to calculate system performance, and 3 to indicate to the test and evaluation community the effects that should be considered when a system is evaluated. Chapter 1 is a discussion of the handbook contents and the use of the handbook. Chapter 2 is a qualitative description of EO and mmw sensors and of the natural obscurants and battlefield-contaminants that may degrade sensor performance. Chapter 3 provides quantitative information on natural obscurants, while Chapter 4 contains quantitative information on battlefield-induced contaminants. Chapter 5 describes sensor performance measures, discusses sensor performance defeat mechanisms and illustrates sensor performance calculations using the quantitative data developed in Chapters 3 and 4.
