NLOS-Aware TDOA-Based UAV Localization: Cram\'er-Rao Bounds, Measurement Modeling, and Experimental Validation
Passive time-difference-of-arrival (TDOA) localization is well suited for tracking non-cooperative unmanned aerial vehicles (UAVs) that do not report their positions. However, its accuracy degrades under the mixed line-of-sight (LOS) and non-line-of-sight (NLOS) propagation that is typical of low-altitude flight. In th...
