Abstract :
The non-destructive testing (NDT) of glass fibre reinforced plastics (GFRP) becomes more and more important. A test setup using a synthetic aperture radar (SAR) at frequencies of 220 - 325 GHz was set up to detect artificial defects in the probe. The paper will present experimental results and will furthermore address the challenges of imaging GFRP samples in a reflection geometry setup.
