Abstract

Target recognition performance for an RCA Shottky barrier staring FLIR with and without target motion is presented together with various minimum resolvable temperature (MRT) measurements obtained using both a 4-bar and a modulation perception requirement, i.e. using the strict requirement to see the 4-bars in the MRT bar pattern and the less restrictive requirement to see some modulation in the displayed image. In addition, both recognition and MRT results for a hand-held thermal viewer having approximately the same limiting spatial frequency as the staring system are presented. The various results are compared and examined to determine if the two dimensional aliasing in staring systems significantly degrades recognition performance relative to conventional scanning systems with similar size detectors and to establish which MRT, vertical 4-bar or modulation, or horizontal 4-bar or modulation is the best predictor of recognition performance when used in conjunction with the Night Vision & Electro-Optics Laboratory (NV&EOL) static recognition model.
