Recognition of naval fleet line type formation based on domain knowledge

Formation is an important means to realize naval fleet tactical intention.So recognition of naval fleet formation is one of the effective methods to discrimination its tactical intention.Starting with systematic study on domain knowledge of naval fleet line type formation,the queue elements of formation and their calculation methods are analyzed and the template' s representation method of naval fleet line type formation is put forward.Based on above analyses,we established coordinate transformation and queue bearing calculation mathematic models that formation recognition requires.And the formation line clustering algorithm based on formation bearing is put forward.At last,the detail algorithm steps are designed in order to convenient for computer implementation,so the recognition algorithm of naval fleet line type formation based on domain knowledge is established.
