Interferometric imagery from a solar powered RPV

Describes the design, integration, and deployment of a compact, high-spectral-resolution imaging interferometer built specifically for use on the Pathfinder solar powered remotely piloted aircraft (RPA) that has been developed under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. Emphasis is placed on the engineering challenges associated with RPA instruments, including low power and weight constraints, extreme thermal and pressure environment, and remote operation. Sample data are presented that illustrate the strengths and weaknesses of the composite RPA/scanned interferometer remote sensing system.
