Official Description

The infrared (IR) tracking system of an interceptor vehicle works by determining the position of an object via the line of sight (LOS) between the vehicle and the object of interest and then feeding that information into the guidance system. In all cases there is a protective window or dome in front of the IR tracking system. If a temperature gradient is formed between the front side and the back side of this protective window, such as might occur in supersonic and hypersonic flight, the measure...

Desktop Instrument for Measuring Boresight Error as a Function of Incident Angle

**Q&A Updates Summary:** Answers added to Q1-Q3 clarifying flexibility on window materials, refractive indices, thicknesses, and temperature gradient types—applicants must specify their approach's capabilities and limitations. Q4 added as duplicate of Q3 with identical answer. Q5 answered with two rejections: sealed windows forming isolated chambers and permanently sealed windows are both outside solicitation scope.
