Special Session 9  会议特别专题 9

Multi-Dimensional Millimeter-Wave/Terahertz Imaging and Sensing for Complex Scenes

Description: Leveraging their inherent physical advantages of short wavelengths and wide bandwidths, millimeter-wave and terahertz (mmWave/THz) radars demonstrate immense potential in ultra-high-resolution 3D/4D imaging and target sensing. They have emerged as core sensors in diverse fields, including autonomous driving, UAV swarms, non-destructive testing (NDT), and the Industrial Internet of Things (IIoT). However, in practical complex environments, high target maneuverability, non-cooperative motion trajectories, and non-ideal background clutter pose severe challenges to high-fidelity radar imaging, robust SAR/ISAR motion compensation, and weak feature extraction. This special session aims to gather the latest research advancements in mmWave and THz radar imaging and sensing, with a particular focus on cutting-edge 3D/4D imaging algorithms, SAR/ISAR signal processing, and the innovative applications of deep learning for radar vision in complex environments.
