Updated NLOS Survey — 2022–2026 Extension

A continuously maintained companion to the 2022 paper, integrating newly verified optical, passive, learned, LiDAR, radar/RF/mmWave, acoustic, THz and emerging NLOS directions. This extension is a living project document rather than a separately peer-reviewed publication.

Explore the literature in 3D

Each paper is a node. Color encodes publication year, node size reflects how strongly a paper sits inside the co-author network, and links connect papers that share authors. Search by paper, researcher, year or research family.

The 3D graph could not be loaded. The survey and paper explorer remain available.
