A Post-Processing Multipath/NLoS Bias Estimation Method Based on DBSCAN

Sensors
Positioning based on Global Navigation Satellite Systems (GNSSs) in urban environments always suffers from multipath and Non-Line-of-Sight (NLoS) effects. In such conditions, the GNSS pseudorange measurements can be affected by biases disrupting the GNSS-

Research on localization scheme of UWB in NLOS environment

Tongxin xuebao, 2008
A localization scheme via UWB suitable for NLOS was given and a TOA estimation based on the strongest path （SP） detection was proposed. The positioning operation between FS and MT was implemented when FS detected two strongest paths from different ...

Geometric Constrained Non-Line-of-Sight Imaging

Normal reconstruction is crucial in non-line-of-sight (NLOS) imaging, as it provides key geometric and lighting information about hidden objects, which significantly improves reconstruction accuracy and scene understanding. However, jointly estimating normals and albedo expands the problem from matrix-valued functions to tensor-valued functions that ...
