Novel Multi-mode Seeker Dome for Miniature Munitions

New applications, such as the Small Diameter Bomb (SDB), require affordable, durable domes with multiple-waveband transparency (i.e., near-IR, MWIR or LWIR, and MMW). Cost effective fabrication of such a dome, will require achieving the optimal balance between competing requirements. Choice of durable dome materials, with suitable transparency, high speed/tight tolerance fabrication techniques, and incorporation of suitable grid/resonant structures to provide EMI shielding and suitable MMW transmission are all critical to the development of a tri-mode seeker dome design for the SDB program. Surmet is developing tri-mode seeker domes for the Joint Common Missile program, working with the Army, Navy and Lockheed Martin. In addition to producing full scale prototypes for evaluation, Surmet is developing alternate configurations which will lead to more affordable dome solutions. Surmet’s experience will be used in evaluating potential dome solutions for this proposed effort. During the proposed Phase I effort, Surmet will perform a trade study on candidate dome materials, dome designs, manufacturing concepts, and applicable technologies for multi-mode seeker domes. Current development activities and technologies, Government and Commercially funded, will be evaluated against specific requirements for the SDB dome. A design concept, will be selected for subsequent development under the Phase II funding.
