Abstract (en)
An early warning tracking system wherein a predefined polygonal zone's position is compared with an uncertainty region projected out in front of each approaching object. Conflicts of the uncertainty regions with the predefined polygonal zone are first considered in two dimensions and finally, in a third dimension only if a lateral intrusion is preliminarily indicated. The uncertainty regions as defined are a function of the position and velocity determination as well as the variances and covariance associated with the positional and velocity determinations.
