Aimed at the multi-platform anti-air combat mission planning excessively depends on the combat experience of commanders, and the commander’s mental load is too large under the information flood, which leads to the rationality and timeliness of the mission planning, multi-platform anti-air combat mission planning technology is studied. By decomposing the air defense task, the frame structure model of the combat mission is designed. According to the analysis results of the planning composition, the models of multi-platform air defense configuration planning, cooperative detection planning, communication networking planning and cooperative strike planning are constructed and combat planning is generated automatically. Thus improving the scientificity and rationality of the mission planning, and provides support for forming rapid combat decision-making capability.
