In order to support the debugging and verifying of the data fusion system, a virtual battlefield environment should be built. This paper mainly deals with the implement technologies in the area of battlefield environment. Based on the theory of system modeling and simulation, this paper presents a new kind of discrete event simulating tactics which combines the event dispatching method with the one of static increment, discusses the motion model for the targets and simulating event model and data creating algorithm of multi-types sensors, gives the method for constructing models of events based on the analysis and conclusion of the situation assessment event. By using the UML modeling technique and object-oriented technology, this paper constructs a well-defined system model, based on which a battlefield environment simulation system consisting of multi-stations, multi-platforms, and multi-sensors is developed.It is proved in practice that all demands of debugging and testing for the data fusion system have been met. Based on the combat scenarios, the battlefield environment simulation system can build a virtual battlefield environment, simulate the process of a combat, meanwhile create simulation data, and send them to the center of data fusion. |
