Time-Difference-of-Arrival (TDOA)-Based Distributed Target Localization by A Robotic Network
IEEE Transactions on Control of Network Systems, 2020Localization and tracking of a moving target arises in many different contexts and is of particular interest in the field of robotic networks. One important class of localization schemes exploits the time-difference-of-arrival (TDOA) of a signal emitted by the target and detected by multiple sensors.

Localization of Underwater Noise Sources Using TDOA (Time Difference of Arrival) Method [PDF]
Journal of the Society of Naval Architects of Korea, 2011 As considerable interests in noise emission from a ship have been increased, the need for localization of noise sources of the marine propeller generating cavitation and singing noise is looming large. In many practical cases, cavitation and singing noise occur on a particular position of the certain blade of the propeller.

Distributed time-difference-of-arrival (TDOA)-based localization of a moving target
2016 IEEE 55th Conference on Decision and Control (CDC), 2016Localization and tracking of a moving target has been established as a key problem in wireless sensor networks, with many algorithms being proposed in this area. In particular, time-difference of arrival (TDOA) localization is considered to be a cost-effective and accurate localization technique.

Anchor Pair Selection for Error Correction in Time Difference of Arrival (TDoA) Ultra Wideband (UWB) Positioning Systems [PDF]
2021 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2021 Ultra wideband positioning systems typically use techniques such as two way ranging (TWR) or time difference of arrival (TDoA) to calculate the position of mobile tags. TDoA techniques require the transmission of only a single packet by the mobile tag, thus providing better scalability, higher update rates and less energy consumption than TWR ...

Multi-cycle estimator for time-difference-of-arrival (TDOA) and its performance
IEE Proceedings - Radar, Sonar and Navigation, 2006Single-cycle time-difference-of-arrival estimator utilises signal's cyclostationarity property of only one cycle frequency. A new approach exploiting the signal's cyclostationarity property of more than one cycle frequency is introduced. Compared with the single-cycle estimator, the method can reduce more estimation variance. The qualitative discussion

Direction-of-arrival methods (DOA) and time difference of arrival (TDOA) position location technique
Proceedings of the Twenty-Second National Radio Science Conference, 2005. NRSC 2005., 2005This paper provides a detailed overview of the various methods for estimation of direction-of-arrival (also called angle-of-arrival) of a radio signal using an antenna array. The array-based directional-of-arrival (DOA) estimation techniques considered here are broadly divided into two different types: conventional techniques, and subspace based ...

Improvement of the Time Difference of Arrival (TDOA) Estimation of GSM Signals Using Wavelets
2000Abstract : The problem of localization of wireless emitters (GSM based) using time difference of arrival (TDOA) techniques is studied. The wavelet transform and denoising techniques are used to increase the accuracy of the TDOA estimate. GSM like signals are simulated using the Hewlett-Packard Advanced Designs System (HP-ADS) software.
