This paper presents imaging results from measurements of an industrially manufactured composite test panel, utilizing two introduced algorithms for data postprocessing. The system employs a planar near-field scanning setup for characterizing defects in composite panels in the 50–67-GHz band, and can be considered as a complementary diagnostic tool for nondestructive testing purposes. The introduced...
This paper presents imaging results of measurements conducted at 60 GHz, using the planar rectangular near-field technique. Utilizing the stated techniques at higher frequencies enables detection of smaller defects, and allows for a small measurement set-up in a laboratory environment. An algorithm based on the Fast Fourier Transform (FFT) has been developed in order to process the data. The paper...
