Abstract : The overall objective of this program was to improve the U.S. Air Force's weapon delivery and navigation capability through a more accurate and reliable determination of vehicle velocity especially designed for optimal integration into an aircraft reference system. The specific objective of the study was to investigate the feasibility of developing a doppler velocity sensor that provides a three-axis velocity estimate with 0.05 percent accuracy while requiring only 0.5 second smoothing of the doppler data. The equipment, including the transmitter, will be entirely solid-state and should not require antenna gimbaling, either electronic or mechanical The findings of the study show that the development of a doppler sensor is feasible and that the desired performance characteristics can be achieved.
