The performance of acoustic passive source localization based on a multiple sensor system does not only depend on the chosen estimation algorithms, but is also strongly correlated to the geometry of the sensor network and the position of the source. This thesis approaches the optimization of the estimation procedure, by utilizing an optimal sensor setup. In order to carry out this optimization procedure for a “quasi-static” source, three performance measures, the Cramer-Rao Lower Bound (CRLB), the Geometric Dilution of Precision (GDOP) and the condition number, are addressed, compared and evaluated. While the two former describe the influence of measurement noise, with known probability density function, the latter is a non-statistical meas...
