Abstract: The processes developed to accurately measure and calibrate the radiation emitted from advanced Electro-Optical Target Simulators are based on: 1) Selecting the best reference datum for the purpose 2) Millidegree accurate thermometry 3) Primary reference blackbody cavities with characterized emissivity 4) A 4th generation Radiometric Telescope 5) NIST Standard Lamps of Spectral Irradiance 6) Capability studies and 7) Uncertainty analysis. Advanced Military Tactical and Strategic Electro-Optical Sensor Systems can sense a given target with increased range in more than one spectral band from UV, through mid wave infrared (MWIR) to long wave infrared (LWIR). The multi spectral operation can also be simultaneous and through a common system aperture. Also, some advanced tactical FLIR systems incorporate laser range finding and target designation through the common aperture at more than one wavelength (eye safe and weapon level).
