Precise Reconstruction Method for Hidden Targets Based on Non-line-of-sight Radar 3D Imaging

Leida xuebao
Non-Line-Of-Sight (NLOS) 3D imaging radar is an emerging technology that utilizes multipath scattering echoes to detect hidden targets. However, this technology faces challenges such as the separation of multipath echoes, reduction of aperture occlusion,

Accurate Multiclass NLOS Channels Identification in UWB Indoor Positioning System-Based Deep Neural Network

IEEE Access
The accurate distinction between line-of-sight (LOS) and non-line-of-sight (NLOS) propagation channels is paramount for precise distance measurement within ultra-wideband (UWB) indoor localization systems.
