Design And Implementation Of Object-oriented Electronic Warfare Simulation System

Electronic warfare plays an extremely important role in modern warfare.The construction of an electronic warfare simulation system is of great help to the development of electronic warfare tactics and the study of electronic countermeasures.Hereby,this paper builds an extensible EW simulation system including early warning radar,reconnaissance receiver and active jammer based on the object oriented method.Firstly,the specific functional and performance requirements of the electronic warfare simulation system are confirmed.Based on these requirements,the operational logic architecture of the entire system is designed.According to the logical architecture,the system is divided into three major modules,and each module consists of several small functional modules.The three major functional modules are: run time infrastructure module,scene resource module and display module.For run time infrastructure module and scene resource module,this article explicitly describes the functions to be implemented by each of the sub-modules that make up the two major modules.Secondly,the design and implementation of the various sub-modules of the run time infrastructure module is described.The run time infrastructure module mainly includes several major sub-function modules such as a simulation engine,a scene management service,a configuration file parsing service,a force generation service,and a command input interface.The design of the engine is to provide platform support for the operation of the simulation system,and the three services are used as the functional resources of the system to accept the engine call and assist the engine in completing the simulation operation.For the simulation engine module,the message forwarding function based on point-to-point communication and the event-driven scheduling function are researched.About the scene management service module,the approach of scene management service providing information support for models in the simulation world is discussed.In the design of the configuration file parsing service,the storage method and structure of configuration information,and the use of file parsing tools are mainly introduced.For the force generation services,the composition of model templates and methods for creating models are discussed.With regard to the command input interface,the storage method and structure of the command data,and the method of parsing the command data are mainly discussed.Thirdly,this paper elaborates on the design and implementation of each sub-module of the scene resource module.Scene resource modules include: coordinate system,entity,and component.All sub-modules of scene resources are used to build simulation scenarios.Coordinate systems provide information such as position and distance to all models,while entities and components are responsible for simulating weapons and equipment in simulation scenarios.For the coordinate system module,five coordinate systems used in the simulation system are mainly introduced,which are the geocentric rectangular coordinate system,the geodetic coordinate system,the northeastern coordinate system,the body coordinate system,and the sensor coordinate system.About the entity module,the composition and execution logic of the entity model are introduced,and the factors to be considered when building a physical model are listed.With regard to the component module,the design concept of the component conceptual model and the specific electronic warfare equipment components are mainly introduced,including the design ideas and implementation methods of the radar,reconnaissance receiver and active jammer.Finally,the process of an electronic warfare aircraft jamming a radar vehicle is designed,and the process is run in the electronic warfare simulation system based on the above design.During the operation,the system displays the battlefield situation and the radar detection state.After actual testing,the feasibility of the simulation system design is verified.
