The detection and tracking of surface targets using airborne radars has been extensively investigated in the literature. However, the state-of-the-art techniques in multi-target tracking do not automatically provide information that is potentially of tactical significance, such as anomalous trajectory patterns. In this paper, recent work that attempts to address this problem that is based on stochastic context-free grammars (SCFGs) is reviewed. It is shown that the production rule probabilities in SCFGs can be used to constrain sizes and orientation of target trajectories and hence lead to development of more refined syntactic trackers.
