Abstract :
In this paper, a distributed sensor network is evaluated concerning its abilities to localize acoustic events based on Time Difference of Arrival (TDoA) measurements. In field trials, the localization accuracy of the sensor network is determined experimentally. The variance of the TDoA measurement error is derived and used in Cramér Rao Lower Bound accuracy analysis and simulations for the given scenario.
