Investigation on Scattering Characteristics of a 3D-printed Sample based on SAR Processing

In this work the scattering characteristics of a 3D-printed sample are being investigated by using a single-polarized and a cross-polarized radar system. The 3D-printed technology has a main contribution in a wide range of applications nowadays. The idea of synthetic aperture radar (SAR) has been utilized to investigate the reflected electromagnetic energy from the 3D-printed sample by setting each of the radar systems in a fixed position and the mounting sample on an x-y positioning table which has been used to achieve rectangular-scan mode for SAR. The data has been ported and processed on a graphical processing unit (GPU) to overcome the complexity issue of the matched filter approach. For better image interpretation, the data has been processed by the median filter in order to reduce noise level while preserving the main image details. The obtained results have been investigated to determine the amount of cross-polarization reflection.
