Abstract

Active incoherent millimeter-wave (AIM) imaging is a recently introduced imaging technique that combines the benefits of passive and active millimeter-wave imaging by using incoherent noise illumination to mimic the properties of thermal radiation. In this work, we investigate the performance of a video-rate AIM imager in an outdoor scenario. The use of active illumination overcomes challenges in other modalities such as sky reflections and other environmental signals. We use a 38 GHz active incoherent millimeter-wave camera with multiple noise transmitters to demonstrate imaging in outdoor scenarios at ranges of more than 9 m.
