Due to the atmospheric absorption in W-band, especially the spectrum around 94 GHz has been the frequency of choice for radar applications in reconnaissance and metrology, but more recently also for indoor security applications. However, for indoor security applications the propagation environment and scale of the application is quite different as compared to the long-range military and scientific...
This paper presents a simplified 2D calculation method based on Huygens' principle for active millimeter wave imaging systems. Although limited in its ability to accurately treat 3D systems, the method is a powerful tool for first order system optimization. We show in this paper how image aberrations such as speckle and glint can be studied and how image enh ancing techniques can be studied with very...
