NVEOD FLIR92 thermal imaging systems performance model

The Night Vision and Electro-Optics Directorate's FLIR92 model predicts minimum resolvable temperature difference (MRTD) and minimum detectable temperature difference (MDTD) for scanning and staring infrared sensors. FLIR92 retains unchanged for two- dimensional MRTD, and incorporates sampling effects and three-dimensional noise more thoroughly than the simple approximations used in the FLIR90 model. The FLIR92 MRTD predictions are shown to be valid for representative scanning and staring systems.
