2012-09-26: Node Localization in Time of Arrival and Time Difference of Arrival Sensor Networks

When: 2012-09-26 09.00

Where: LTH, E-huset, E:2116

Speaker: Kalle Åström, Dept. of Mathematics


In this talk I will presents recent progress in sensor network calibration that arise in TOA and TDOA measurements. Such calibration arise in several applications such as calibration of (acoustic) microphone arrays, calibration of wifi-transmittor arrays and radio antenna networks. Several interesting geometric problems arise in this area, e g from full node calibration, to resection, using far-field approximation or not, assuming TOA or TDOA and finally dimensionality of the spaces spanned by the networks.

The research is motivated by e g indoor navigation problems and has been initiated by the ELLIIT (a collaboration between Lund, Linköping, Halmstad and Blekinge).

In the talk I will outline some of the most recent results in our research group.
