Plot Enchaining Algorithm: A Novel Approach for Clustering Flocks of Birds

In this study, an intuitive way for tracking flocks of birds is proposed and compared to simple cluster-seeking algorithm for real radar observations. For group of targets such as flock of birds, there is no need to track each target individually. Instead a cluster can be used to represent closely spaced tracks of a possible group. Considering a group of targets as a single target for tracking provides significant performance improvement with almost no loss of information.
