This paper presents the design of an active short range imaging system in the Ka-band (26.6 - 40 GHz). The sensor is a multistatic linear array which is moved perpendicular to the array dimension for the purpose of 3D imaging. By sequentially switching on the transmitters and simultaneous reception of the scattered field by each receiver, a fast sampling of the 2D aperture plane is achieved. To reduce...
This paper investigates the feasibility of human body imaging by means of microwave ultra-wideband (UWB) radar with a planar aperture. Its potential imaging capability is at first estimated by numerical simulation which demonstrates the dependence of cross-range resolution and side/grating lobe level on both the operational bandwidth and spatial sampling. Experimental results from 2-D synthetic aperture...
