Abstract 

Recently, there has been a significant interest in employing\$nhigh frequency radar imagery for many industrial oriented and security\$napplications. The quality control of aeronautics composite multi-layered\$nmaterials and structures through Non-Destructive Testing (NDT) is the\$nmain focus of this study. The main motivations for using this technology\$nare: it allows penetration of most non-metal and non-polarized\$nmaterials, it provides the ability for three-dimensional (3-D) imagery\$nand in-depth information, and the millimeter waves (mmW) pose no health\$nrisk to the operator. The main goal of this research is to develop an\$nintegrated, semi-automatic and near real-time mode-operated image\$nprocessing methodology for frequency-modulated continuous-wave (FMCW)\$nmillimeter wave images with center frequencies around 100 GHz and 300\$nGHz. The proposed methodology firstly foresees to process reflectance\$nand transmittance 3-D imagery by extracting areas of interest and\$nobject's boundaries at two operated frequencies. Then, the detected\$nareas are subjected to a multi-source database and integrated by a\$ndecision tree algorithm. The fused information is used to identify\$ndefects and in-homogeneities within the objects. Finally, the\$npost-processing phase examines and evaluates the spatial accuracy of the\$nextracted information.
