Multilateration Station Selection Method for Airport Surface Surveillance
Huang Zhong-Tao · Telecommunication Engineering · 2009
For a multilateration(MLAT) system of TDOA(Time Difference of Arrival) for airport surface surveillance,if one of MLAT stations meets proliferation of time measurement error,it will lead to considerable reduction of position precision.Thus a new method of station selection is presented in this paper for quickly determining which station has excess time error.Firstly target positions are estimated by smooth filtering, then accumulative error judgments for position and TDOA measurements are made based on estimation values.And Monte - Carlo simulations for a specific airport show the validity of the method.
