Abstract :
In this study, two different applications are performed. An application of concealed object detection is firstly studied through millimeter-wave inverse synthetic aperture radar (ISAR) imaging. For this purpose, near-field W-band ISAR measurements of one centimeter metallic and dielectric cube targets covered by distinct textile materials are carried out in an anechoic chamber room. Then, the images are reconstructed by using back-projection ISAR imaging technique. Then, the performance of the technique is quantified from the resulted images by using the accuracy and quality metrics. An application of a concealed weapon is also handled using millimeter-wave tomography imaging. The tomography imaging of concealed weapon located behind styropor foam wall is performed. Then, the images are reconstructed by using a method which calculates polarization currents on the object surface. The results obtained are finally shown.
