Abstract
A system for detecting radio frequency (RF) signals includes a radome including one or more phase change material (PCM) layers disposed on an inner surface thereof and a sensor at least partially disposed within the radome. The system also includes a heat source arranged such that it can direct heat toward the inner surface of the radome and a controller that causes the heat source to direct heat towards the inner surface of the radome such that a frequency selective surface (FSS) is formed thereon.
