A Calculation Method of Track Quality

Aimed at accurately selecting data source in calculation of track association, the track quality(TQ) assessment method based on two-points extrapolate is studied. The method takes into account the influencing impact of the TQ calculation including platform navigation error, the radar measurement error and extrapolation error. The simulation results of various types of error on the TQ calculation are analyzed. It is verified that the method is simple and feasible, be able to accurately evaluate TQ and be able to adapt to different platforms and different sensor requirements.
