Mathematical Model of FLIR Performance

Abstract

In this technical memorandum a set of equations is developed which permits one to calculate acquisition, classification and identification ranges for ship targets when viewed by an airborne forward looking infrared (FLIR) imaging device. Inputs to the model are the average dimensions and aspect angle of the target, the average ship-to-background temperature difference, the surface air temperature and relative humidity, and the nominal resolution, noise equivalent temperature difference and altitude of the FLIR. Novel features of the model are the use of square picture elements (pixels) to establish criteria for acquisition, classification and identification and the relating of pixel size to the minimum resolvable temperature difference of the FLIR.
