Abstract
A wind turbine blade inspection system includes a frequency modulated continuous wave radar system configured to be movable with respect to a wind turbine blade while transmitting reference microwave signals and receiving reflected microwave signals and a processor configured for using a synthetic aperture analysis technique to obtain a focused image of at least a region of the wind turbine blade based on the reflected microwave signals.
Claims20
A wind turbine blade inspection system comprising:
- a frequency modulated continuous wave radar system configured to be movable with respect to a wind turbine blade while transmitting reference microwave signals and receiving reflected microwave signals;
- and
- a processor configured for using a synthetic aperture analysis technique to obtain a focused image of at least a region of the wind turbine blade based on the reflected microwave signals.
A method for inspecting a wind turbine blade comprising:
- using an inspection system for transmitting reference microwave signals towards the wind turbine blade and receiving reflected microwave signals from the wind turbine blade while moving the inspection system with respect to the wind turbine blade;
- obtaining a focused image of at least a region of the wind turbine blade based on the reflected microwave signals using a synthetic aperture analysis technique.
