Localization algorithms for asynchronous time difference of arrival positioning systems
An asynchronous time difference of arrival (ATDOA) positioning system requires no time synchronization among all the anchor and target nodes, which makes it highly practical and can be easily deployed. This paper first presents an ATDOA localization model, and then primarily focuses on two new localization algorithms for the system. The first algorithm is a two-step positioning algorithm that c...
متن کاملSmall Boat Bearing Localization using Time-Difference of Arrival
This tutorial involves implementing sonar processing algorithms and applying them to real underwater hydrophone data collected in the ocean. The goal of the tutorial is to learn how to apply the time-difference of arrival (TDOA) method to acoustic data recorded on two hydrophones to obtain a bearing estimate. TDOA processing is a classic passive sonar problem, and is also forms basis for many o...
متن کاملHybrid Uplink-Time Difference of Arrival and Assisted-GPS Positioning Technique
A hybrid positioning system is merely one in which multiple systems are used for positioning purposes. This virtually always, though not necessarily, includes Global Positioning System (GPS) as it is the only global positioning network currently. Combination of mobile network and GPS positioning techniques provide a higher accuracy of mobile location than positions based on a standalone GPS or ...
متن کاملReliability Measurement of Time Difference of Arrival Estimations for Multiple Sound Source Localization
Time Difference Of Arrival (TDOA) estimates are used for passive acoustic single sound source localization with microphone arrays. The technique of choice in most systems for TDOA estimation is the Generalized Cross-Correlation (GCC) method [1]. For a multi-sound source scenario, cross-correlation terms of the active sound source signals as well as noise and reverberation effects complicate the...
متن کاملConfidence Scoring of Time Difference of Arrival Estimation for Speaker Localization with Microphone Arrays
Microphone arrays can be employed for passive acoustic source localization using time difference of arrival (TDOA) estimates in microphone pairs. The most common method for this TDOA estimation is the generalized crosscorrelation (GCC) method which is also used in this work. In an office room environmental noise influences and reverberation effects complicate the TDOA estimation and aggravate a...
