Descripción
This work presents a method to estimate and correct undesirable effects caused by troposphere propagation and non-perfect ground station synchronization, in the context of target tracking with a Wide Area Multilateration (WAM) system. Correlation of opportunity traffic emissions is used to overcome the difficulty of installing reference beacons simultaneously visible to all the base stations. The architecture of this method is based on the possibility of decoupling the target position determination problem and the systematic error estimation problem. On one hand, given the non-linearity of the signal measurement (Time Difference Of Arrival) with respect to the target state vector, the target position is determined by using an Unscented Kalman Filter (UKF). On the other hand, an Extended Kalman Filter (EKF) is used to estimate the systematic error along time. The relationship between both filters is established at their respective update stages. Experiments using deliberately adverse scenarios have been performed to test the reliability of this method.
