Abstract: The application of visualization systems in digital fire control systems is discussed. Methods of multi-dimensional visualization are put forward, both the method of plane projection and of information layers are used to analyze the character of data and information for a digital fire control system. A system of visualization for digital fire control is given. According to the concept of metaphor in visualization, graphic elements can be designed, and through considerations from human engineering, the design of interfaces is emphasized, and a multi-model interface is developed. Concrete realization adopting object-oriented program design is provided, so that integrated, audio visual and direct visualization interfaces are developed.
