AbstractABSTRACT: As more and more advanced hypersonic weapons are developed, vehicle temperatures are expected to near 1250°K (977°C); as flight times increase, these temperatures are expected to saturate the entire vehicle. Typically, forward-looking RF and IR sensors are collocated in the same protective radome, which degrades the performance of both systems. FIRST RF proposes a significantly different approach to the challenge of High-Speed Weapon Radomes by relocating the antenna sensors to alternate regions of the weapon. FIRST RF has developed a revolutionary new conformal, high temperature, forward-looking, high gain antenna, suitable for seeker applications in the hypersonic environment. The solution makes use of unique, end-fire antennas that are constructed from conformal, high-temperature dielectric materials. The proposed work is targeting seeker system application for Ku- and Ka-band. The part count is low and the construction method is very simple and robust. The proposed Phase II program will fabricate and test a small array demonstrating the performance benefits. BENEFIT: Thermal management is the greatest challenge to this particular application. FIRST RF believes that we offer a practical approach to solving the antenna design. It leverages proven radiator technology and addresses thermal impact on the antenna. The specific benefits are: 1) Thermal impact on the antennas is managed while maintaining overall platform capability and performance. 2) The antenna design is such that the radiation pattern is optimized and efficiency is maximized, while ensuring environmental operation.
