A Joint Positioning Algorithm of TOF and TDOA Based on Weighted Centroid [PDF]
Aiming at the problem of low accuracy and positioning divergence in the UWB TDOA positioning mode with the positioning scenarios such as severe noise environments or tags near the base stations, a new TOF and TDOA joint positioning method was constructed

TDOA source positioning in the presence of outliers [PDF]
Source localisation using time difference of arrival (TDOA) measurements has drawn considerable attention in the past few decades. The presence of outliers in TDOAs could deteriorate the localisation performance significantly. Under the reasonable assumption that outliers are sparse and they do not dominate in the raw measurement set, a computationally

A two‐stage iterative method for short‐wave source localisation
Short‐wave source localisation has an important role in many fields. A two‐stage iterative algorithm is proposed based on the ionospheric virtual height (IVH) model using the direction of arrival (DOA) and time difference of arrival (TDOA) measurements ...
