The innovative radar scanner from Fraunhofer IAF enables defects in the material composition of the wind turbine blades to be detected with significantly greater accuracy. This cuts production and operating costs.

In the project InFaRo, an innovative measuring system based on radar and thermography is developed in order to detect faults in GFRP components during production. Task of the Fraunhofer IAF is the radar system development and characterization. The radar components are based on the IAFs in-house mHEMT process. Due to its high transit frequency and excellent noise characteristics, extremely precise radar sensors can be realized.
