Abstract

Active millimeter wave imaging technology is emerging, which has the potential to yield much more information when one has control over the illumination parameters. Image processing of this kind of images is almost inexistent in literature. In this paper, we propose multidimensional illumination techniques to improve the mm-wave image quality. Multi-angle, multi-frequency, and cross-polarization illuminations were implemented to obtain multidimensional images. Principle Component Analysis (PCA) and clustering analysis were applied to process the results.
