Optimal source localization in a real radio channel

In this paper, TOA localization model is presented for passive source localization. Localization problem is formulated as an optimization problem with the sum of squared errors as the objective function. Gauss-Newton optimization method is applied in order to determine optimal transmitter location. We considered radio channel in the presence of Gaussian noise. Computer numerical simulation results in MATLAB are presented for linear and nonlinear TOA localization methods, as well as their mutual correlation.
