Under the condition of information warfare, a variety of reconnaissance and surveillance equipments(such as satellite, radar, UAV group, etc)can acquire massive battlefield information and data. How to effectively utilize the massive multiple source isomerism information to improve the intelligence degree and strike precision of UAV is a hot research field. Based on the introduction of the development status of knowledge graph and artificial intelligence, the knowledge graph is constructed aiming at the goal of guiding UAV to complete intelligent strike, and a solution is given combining with specific war requirements and scene characteristics.
