Abstract
A method for analyzing ballistic trajectories comprises determining invariants for known ballistic objects, defining a reference graph having nodes corresponding to the invariants, and defining a query graph having nodes connected to nodes of the reference graph corresponding to anticipated invariant queries to be made using the query graph. One or more sets of invariants corresponding to trajectories of one or more observed objects are input into the reference graph and traverse through the nodes of the reference graph, leaving a record in the nodes traversed. A query is selected for the query graph corresponding to one or more range of invariants, the query generating a query result identifying the nodes of the reference graph that satisfy the query. Identifying each of the observed objects identified by a record in the identified nodes determines which of the one the observed objects satisfy the query.
