ABSTRACT:Active millimeter wave seekers are needed at a lower cost point in order to improve load-out for future air-ground missions. Our approach to developing a $15,000 RF seeker is to create a passive electronically-steerable antenna that is driven by COTS amplifiers and protected by COTS limiters and is built from low cost packaging techniques. Our PESA will use low-loss switch devices in a new way that minimizes RF loss while providing affordable mass production. A near-hermetic coating system will protect chip-and-wire electronics while providing electromagnetic shielding. Phase I will develop performance and cost predictions for our approach.BENEFIT:The proposed technology has application to a variety of weapons platforms at numerous frequency bands. Our Phase I technical approach is specifically tailored for inclusion in a either an X-band, Ku-band or Ka-band seeker for next-generation self-guided munitions such as an improved Small Diameter Bomb II (SDB-II) or Joint Air-to-Ground Missile (JAGM). Identifying additional product insertion points will be a topic of our Phase I and Phase II research. Beyond weapons platforms, there are several other military and commercial applications for the RF seeker technologies to be developed on this program. Radar sensors as well as radios are in need of affordable solutions to electronic beam-steering.

This proposed program addresses the need for a spaceborne phased array radar system that operates simultaneously at multiple frequency bands for future NASA remote sensing missions dedicated to answering emerging fundamental questions associated with aerosols, clouds, air quality and ecosystems. We will deliver active, electronically scanned array tiles at Ku- and Ka-band utilizing the Nuvotronics PolyStrata® technology for integration alongside an electronically scanned W-band array to form a tri-band system. The PolyStrata® wafer-scale microfabrication process, with capabilities to monolithically integrate dielectric-free antennas with air-coax feed networks in 3D, is a key enabler for achieving state-of-the art performance requirements and manufacturing scalability. Unprecedented power levels will be achieved by integrating state-of-the art GaN MMICs into the PolyStrata front-end architecture.
