Multi-station TDOA Localization Method Based on Tikhonov Regularization

In this paper, we consider localization using multi-station TDOA, aiming at the invalidation of localization caused by the irrationality of the sensor distribution, proposed a new robust localization algorithm based on Tikhonov regularization method. The new method gives attention both to the resolution and the square error of the estimation results, restrained the uncertain part while keeps the certain part of the observation noise, and guarantees the validation of new method on multi-station TDOA localization even the the sensor distribution irrationally. It has a high vallue of engineering applicaton, the simulation results varify the validity of the algorithm.
