Abstract : Caliber 30 Lexan cylinders, 1/4 inch saboted Lexan spheres, and 1/4 inch saboted ceramic spheres were fired. Instrumentation was developed to measure the radiation emitted from these models for various range conditions. The investigation was restricted primarily to the near infrared spectral region, but some measurements were made in the visible region. Some preliminary results are presented to show that this instrumentation can provide reliable measurements of radiation from the model and its wake. (Author)
