Abstract

The present invention provides for a heretofore unknown radome construction which utilizes core materials heretofore unrealized in radome construction. These core materials include a class of microcellular foams and polycarbonate honeycomb. In one embodiment, the polycarbonate honeycomb is configured with a circular shaped primary cell structure. In another embodiment, the radome is fashioned as a hybrid core configuration consisting of an impact resisting core material and a conventional core material. In another embodiment, the impact resisting core is positioned at the forward nose section of the radome while the conventional core material is positioned in the aft section of the radome.
