Modeling and simulation of battlefield environment is the key and difficult problem in the military simulation. This project considers the technical requirements of operational effectiveness simulation, and research the digital twin driven modeling and simulation method for battlefield environment. By taking the radio frequency environment and infrared environment as research object, it aims to break through the discrete event based modeling method of the battlefield environment, and realize the hybrid model and data driven simulation running method of virtual and real battlefield environment. It can solve the problem that the environmental impact in the existing combat effectiveness simulation is too simplified or does not consider environmental factors and their effects at all. It can also solve the problem of lack quantitative analysis and mechanism research of environmental impact on equipment and combat, as well as the problem of unable to objectively and effectively reflect the process of environmental changes and their effects. Based on the proposed digital twin driven modeling method and simulation of battlefield environment, a virtual twin battlefield environment prototype system for combat effectiveness evaluation is constructed, combined with typical application scenarios such as electronic countermeasure equipment combat effectiveness evaluation, to conduct empirical research to verify the effectiveness and feasibility of the method. This project will provide a theoretical method basis for the application of digital twin in the military field. It has great theoretical significance and application value for realizing all elements virtualized reconstruction of the battlefield environment, and promoting the simulation operation of two-way equal interaction between the virtual and the reality.
