Track Quality Evaluation Method Research on Tactical Data Link

Track quality (TQ) evaluation of tactical data link is most crucial content in track processing, and is also the basis of tactical data link. In this paper, a new assessment method is presented to calculate the TQ. At first, TQ area equation defined in the U.S. Army tactical data link formatted message standard (TADIL) 6016B is introduced. Meanwhile, according to the educing and analyzing, this paper shows that the track quality in U.S. Army data link is defined according to the ellipse expression based on the χ² distributing, and the TQ acreage value equals to the acreage of ellipse. Moreover, a new method of distance measurement on TQ value is proposed. At last, simulations show the affection of the geography location error, radar measurement error and extrapolation error on the TQ value.
