Abstract
A radome useful with high-speed guided missiles has an inner conical shell made of a strong, high temperature resistant material transparent to radiant energy in the operative frequency range of a sensor mounted inside the shell. An outer ablative layer covers the exterior surface of the shell. This layer is made of a material which is also transparent to radiant energy in the sensor frequency range and which melts or sublimes and displaces from the shell at a predetermined elevated temperature and/or velocity during high-speed flight. The thickness of the ablative layer is selected so that it compensates for increased thickness and/or refraction resulting from thermal expansion of the shell, thereby minimizing guidance errors.
