Block-Segmented Spatial-Spectrum Imaging for Near-Field Millimeter Waves with Microwave-Photonic Broadband Reception

Active millimeter-wave (mm-wave) imaging uses non-ionizing electromagnetic radiation to detect concealed metallic and dielectric objects and is an important technology for personnel security screening. However, practical security-screening scenarios typically involve short standoff distances and small apertures: the li...
