The measurements are gained by exploiting the signal impinging from an unknown moving emitter. First, a combined set of TDOA and Angle of Arrival (AOA) measurements is processed using the Maximum Likelihood Estimator (MLE). Then, a Gaussian Mixture (GM) filter is used to solve the tracking problem based on TDOA and Frequency Difference of Arrival (FDOA) measurements. In Monte Carlo simulations, the superior performance of the combined methods in contrast to the single TDOA approach is shown and compared with the Cramér-Rao Lower Bound (CRLB).enText/Conference Paper1617-5468
