Abstract : The current work is a preliminary study to planned direct measurement of the infrared emissions of a projectile in flight, from which surface temperature will be estimated. If the planned experiment is to be meaningful, the projectile surface temperature must be high enough such that the incident infrared radiation is significant enough to e measured by the detectors. In this report, detector threshold is calculated and compared to the computed infrared radiation reaching the detector from an M735 projectile nosecone at a distance from the muzzle of 225 meters. In the wavelength band 2.0 - 2.5 mu, the results predict that the detector will not be able to see the projectile emissions, and in the wavelength band 3.5 4.0 mu, the results show probable detection of most of the projectile only if the flow is turbulent...
