ABSTRACT:
A method and apparatus wherein a Genetic Algorithm or an Evolutionary Program is used as an intelligent search technique addresses the problem of assigning sensor reports in multi-target tracking with one or more sensors. The inventive technique of tracking objects includes receiving sensor reports from at least one sensor over multiple time scans; formulating hypotheses as lists of associations between the sensor reports; constructing at least one track for each of the hypotheses; scoring each of the hypotheses; searching through a portion of the hypotheses, using an intelligent search algorithm, to find a good hypothesis; and determining the state of the tracked objects.
