Calibration of antenna arrays for aeronautical vehicles on ground

Aerospace Science and Technology, 2013
Abstract Antenna pattern and characteristics change significantly when antenna arrays are placed on platforms like aeronautical vehicles. Calibration of antenna arrays is an important and costly process for such cases. In this paper, a method is proposed for the offline calibration of a direction finding antenna array mounted on a UH-60 helicopter ...

Aeronautical and space vehicle control in dynamic sliding manifolds

International Journal of Control, 2003
Abstract Multiple loop multiple time scale sliding mode control technique based on dynamic sliding manifold is developed and applied to aeronautical and space vehicle control. Minimum and nonminimum phase output tracking problems for aeronautical and space vehicles are addressed in dynamic sliding manifold. Numerical examples of the flight controller

Ground calibration of antenna arrays for aeronautical vehicles

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
When antenna arrays are placed on platforms, antenna patterns and antenna characteristics change significantly. Calibration of antenna arrays becomes an inevitable and important task to correct the imperfections due to the antenna surroundings. In this paper, a method is proposed to calibrate the direction finding antenna array on a UH-60 helicopter on

Propellant Technologies: Far-Reaching Benefits for Aeronautical and Space-Vehicle Propulsion

Journal of Propulsion and Power, 1998
Rocket propellant and propulsion technology improvements can be used to reduce the development time and operational costs of new space-vehicle programs. Advanced propellant technologies can make the space vehicles safer, more operable, and better performing. Five technology areas are described: monopropellants, alternative hydrocarbons, gelled hydrogen,
