To meet the demand of different angle visualization on real arms maneuver flight data, a real arms maneuver reappearance system driven by flight data was proposed. The system constitute, Primary function and realization method were introduced. The system constitute diagram and signal floor diagram were provided, and some key technologies were analyzed including flight data interpreting, flight data singularity omitting, flight data interpolating, two-dimension simulation based on MapX and three-dimension flight reappearance based on Mantis. The system has realistic scene and abundant information, and it bases on fact. The system provides army and department with new platform to evaluate the real arms maneuver and to study new tactics.
