Abstract:n today"s complex and dynamic battlefield environments, accurate evaluation and optimization of weapon performance are of paramount importance. Research has successfully developed a comprehensive combat scene visualization simulation system using the STK platform, enabling comprehensive simulation and evaluation of weapon systems in such complex environments. The study focuses on offline scene modeling techniques, model animation optimization, and various methods of data processing and transmission. Through experimental testing, the simulation system has been shown to play a critical role in evaluating and optimizing weapon performance, tactical planning and military exercises, real-time decision support, and weapon system integration validation across multiple domains. The research drives technological innovation and expands research directions, with a focus on ensuring cost-effectiveness. By deeply understanding and simulating battlefield environments, it provides strong support for enhancing weapon system performance and addressing complex operational scenarios, laying a solid foundation for future military applications and decision-making processes.
