dc.description.abstract A technique for thermal infrared (8-14 micrometers) synthetic image generation (SIG) was demonstrated that yields improved radiometric accuracy. This process utilizes the LOWTRAN 6 atmospheric propagation model and computer graphics ray-tracing techniques. A scene is created by placing faceted objects into world coordinates with rotation, translation, and scaling parameters. Each facet is assigned a material index and temperature. This index points to angular emissivity data for that material. LOWTRAN 6 can incorporate a sensor response function when calculating data files for the atmospheric transmission, upwelled and downwelled radiances, and temperature-to-radiance conversions. Ray-traced imagery is generated and discussed. The image is then further processed using convolution to represent the modulation transfer function of the imaging system. The final infrared synthetic image is then compared to an actual thermal image. An average apparent temperature difference of 2.50C is reported with a 1.52C standard deviation. These temperatures fall within predicted error analysis limits. en_US
