Ku/Ka-Band Electrically-Scanned Line Array for Tri-Band Cloud and Precipitation Radar Applications

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.
