W-band three-dimensional surveillance imaging system
Millimeter-waves are nonionizing, readily penetrate common clothing material, and are reflected from the human body and any concealed items. In this paper, a 3-D imaging system is proposed. It works in W-band in order to achieve high resolution. The image reconstruction algorithm used to form a focused image at near field is based on spatial frequency domain, and process of algorithm is displayed detail. The experiment results show that the resolution of the image is better than 5mm. This system is described in detail along with imaging results.
