Non-line-of-sight propagation in object localization: a survey
Gong-kuang zidonghua, 2020 Due to the existence of obstacles, none-line-of-sight(NLOS) propagation is common in localization scenes like mines, which causes refraction, reflection, diffraction and scattering of localization signals, leads to the increase of ranging error, and ...
