1. A method for tracking a moving target, comprising: receiving a plurality of detections obtained during a surveillance period from at least one sensor monitoring at least one target moving along a respective discernable trajectory; identifying a respective linear approximation of at least one of the respective discernable trajectories; associating a respective first subset of the plurality of detections with each of the respective linear approximations; identifying for each of the associated first subsets, a respective quadratic approximation of the respective discernable trajectory; and associating further, for each of the associated first subsets, a respective second subset of the plurality of detections with each of the respective quadratic approximations.
