Abstract : The design criteria and the miss distance scoring capability of an infrared radiation detection technique are evaluated. The technique employs two detectors and a reflecting cone optical system to provi e the 360 degrees viewing geometry necessary for scoring. The study includes basic design considerations for the reflecting cone optics and associated detection circuitry. Effects of source strength, missile trajectory, and background on scorer performance are considered. A prototype optical unit and preamplifier were fabricated to confirm the optical analysis and determine system detection performance. Laboratory test results indicate that missile scoring can be accomplished with the prototype unit out to miss distances of 2340 ft for a space background and typical missile exhaust plume sources. In a clear sky air environment, scoring is possible out to 321 ft. Before optimization or additional development of the system is attempted, scoring accuracy field tests should be conducted with the prototype unit using projectiles such as tracer and/or 5-in. HVAR munitions. (Author)
