1. An improved method for radar tracking of ground traffic at an airport to reduce the occurrence of runway incursions, comprising the steps of:

  • employing a radar system to continuously sweep an airport area and detect individual major components of individual fixed and moving objects within the sweep area on and adjacent to a specific runway;

    combining and centroiding the images from several individual aircraft components detected to provide an estimate of the true center and orientation of the aircraft and to form a stick-figure tracker for the aircraft being observed;

    identifying the aircraft observed by comparing the stick figure tracker obtained with known stick figure trackers for the type aircraft suspected in the area;

    measuring the range and bearing of the individual aircraft components; and

    tracking each individual component in the stick figure tracker to thereby indicate and predict the precise relative location of critical aircraft physical components and give instantaneous information of any change in aircraft bearing between radar sweeps.
