Data Fusion based on data from several ground based target tracking radars, EOTs and INS sensors is a complex problem as the data contains different systematic errors, time stamps and time delays. This paper presents some practical solutions to correcting the sensor errors like bias, estimation of measurement and process noise, time stamp and time delay error handling. The solutions are implemented in a data fusion scheme for a tracking application. The data fusion scheme is tested on simulated data of a moving target and also applied to real data of an aircraft tracked by three ground based radars.
