System and method for inspecting a wind turbine blade

摘要

A wind turbine blade inspection system (40) includes a frequency modulated continuous wave radar system (46) configured to be movable with respect to a wind turbine blade (22) while transmitting reference microwave signals (66) and receiving reflected microwave signals and a processor (42) configured for using a synthetic aperture analysis technique to obtain a focused image of at least a region (116) of the wind turbine blade (22) based on the reflected microwave signals.
