FIRST RF Corporation proposes the development and integration of a low-cost, low-SWaP, Integrated System for Avoidance of Ice-producing Airborne Hazards (ISAIAH). This system will be lightweight (~15 lbs) and draw minimal prime power (less than 100W), but will dramatically widen the window of available operating conditions to Navy and Marine Corps aircraft systems by providing realtime 3D ice hazard detection. The ISAIAH system will be comprised of a ruggedized, near-COTS radiometer system by Radiometrics Corporation, and augmented with a robust 2-D scanning antenna by FIRST RF Corporation, which will allow the system to rapidly create a 3D mapping of supercooled liquid water in the aircraft s vicinity, allowing the pilot to avoid icing and permitting flight in conditions normally precluded because of the danger of icing.
