| Abstract | Abstract A new testing method for composite materials was investigated in this paper. A synthetic aperture radar (SAR) in the W-Band from 75 to 110 GHz served as imaging system. The lateral resolution is around 3.0 mm and the range resolution around 4.3 mm. The system was tested with five glass fibre reinforced plastic (GFRP) samples that have several flat bottom holes to represent defects. The defects were detected with magnitude and phase images. Since the reconstruction returns a 3-D image of the sample also the time-domain data was examined in magnitude and phase. Using the phase and magnitude information together all defects were detected. |
