Research on Flight Type Recognition Technology Based on Information Fusion

It is one of the important tasks in air defense safety to identify the flight type attributes of the flight target and then determine the threat level of the flight target. Aiming at the problem of flight target type recognition, this paper combines pattern recognition based on knowledge graph and weighted D-S evidence theory method, and realizes the type recognition of flight target with the help of flight target knowledge graph. The proposal and application of this method are beneficial to improve the automation degree of model recognition.
