摘要
Active incoherent millimeter-wave imaging is a recently introduced technique that combines incoherent signal transmission with interferometric antenna arrays. This essentially minimizes coordination between transmit and receive apertures and reduces the very high sensitivity requirements found in passive interferometric antenna arrays which capture very low power thermal signals. In this work, we explore short-range image reconstructions of conductive and dielectric targets from a compact 24-element 38 GHz active incoherent imaging array emitting random noise. We include experimental measurements in a semi-anechoic environment.
