英文摘要：
A platform allowing a digitized weapon system＇s simulation techniques and tactics to be simulated has been planned and implemented. It meets requirements for the demonstration, analysis, design and simulation needed for research and development of close-in weapon systems （CIWS）. CIWS demonstration, design, study and testing were supported. CIWS responses were simulated in the 3D visualization framework and Vega Prime. The technology to calculate the trajectories of rounds and missiles, to operate the weapons and to detect real-time collisions was deeply studied. Flight modeling of rounds and missiles was improved based on kinematics and kinetics theory. A moving mechanical model of a naval CIWS was proposed; it improved the ability to detect collisions of high speed objects. Implement of the CIWS simulator validated the practicality of the proposals and will improve the accuracy of simulations.
