Research On Radar Networking Method And Electromagenetic Environment Simulation

With the development of computer science, computer simulation training system for military is globally favored because of its low-cost and high-universality. Especially for the air force, the application of computer simulation training can significantly reduce training costs, while increase training time and improve the quality of personnel quickly. The Electromagnetic Environment Simulation System discussed in this thesis is a subsystem of flight simulation training system designed for XX training center, the subsystems is aimed to simulate complex electromagnetic environment, provide a realistic battlefield environment for other subsystems, thus improves the simulation of authenticity. Based on the completion of the simulation training system, this thesis extends the system function and integrates network radar detection model into this system, which both increase the strength of electronic countermeasures and improve the authenticity of the whole system.This thesis uses the particle swarm optimization algorithm to achieve the optimal station. And Dynamic optimal weighting method is used as a method of information integration. Ultimately, these two methods are combined to achieve a radar network application in the electromagnetic environment simulation system. The main contents of this thesis are as follows:1. The electromagnetic environment simulation system is introduced. Then network radar simulation is completed and integrated into the system. PSO is selected as the optimal deployment implementation after contrast of the genetic algorithm, ant algorithm and particle swarm optimization. According to the demands of the project we get a mathematical model and export fitness function & constraint conditions that PSO needs. According to this, the optimal deployment of the radar is completed. And then, with the analysis of the optimal weighted average method, we study the dynamic optimal weighting method. The results of the experiments which information fusion method are given.2. Combining with the design pattern, the design of the electromagnetic environment simulation system is given, which uses the observer pattern and mediator pattern to realize the system model abstraction that inverses dependency and improves the working efficiency of the system. The interface is designed and coded with MFC, and added electronic map control that can intuitively display the actual location of units. The interface can also display specific information of radar detection with the MFC control, which improves the ability of human-computer interaction. Then the entire software system coding realization is finally completed.This thesis extends the electromagnetic environment simulation system by integrating network radar detection model into this system, which can reinforce the capability to resist the stealth units and active jamming and improve the effectiveness of training for simulation training staff.
