Abstract

The performance of modern Forward-Looking Infrared (FLIR) systems is vital to preserving the lives of military personnel and civilians. Proper test and evaluation processes enhance system integration and provide useful data for system improvements and tactical implementation. Such processes are also necessary to effectively compare modeling and laboratory data with in-situ flight data. In this paper we discuss the test and evaluation processes typically used for infrared imaging systems and discuss some methods of correlating laboratory and modeling results with flight data. We will present a hypothetical infrared imaging system, demonstrate how it is put through various stages of testing, observe sample hypothetical system data results, and discuss some reasons for selecting specific testing facilities and locations. Additional discussion will focus on preliminary testing considerations such as selection of ground targets for Minimum Resolvable Temperature Difference tests and the selection of proper target FLIR test patterns. Finally we will mention future testing challenges such as short-wave infrared systems and the validity of current assumptions used when testing mid-wave infrared systems.
