The Takeaway
Scientists used ordinary communication signals to reconstruct 3D environments without needing cameras or expensive sensors. This means devices could navigate through thick fog or total darkness simply by using the radio waves they already use to talk to each other.
From the abstract
Robust 3D environmental perception is critical for applications such as autonomous driving and robot navigation. However, optical sensors such as cameras and LiDAR often fail under adverse conditions, including smoke, fog, and non-ideal lighting. Although specialized radar systems can operate in these environments, their reliance on bespoke hardware and licensed spectrum limits scalability and cost-effectiveness. This paper introduces Rascene, an integrated sensing and communication (ISAC) frame
