| In the tactical Internet,radios play an important role in tactical communications,and the operational proficiency of fighters on radios often determines the success rate and quality of radio communications.In order to improve proficiency,combat personnel will undergo rigorous radio training.When conducting radio training,how to enable trainees to master radio operations faster,more accurately and more proficiently,and how to incorporate factors such as real terrain and communication interference into the training has become the key to building a radio simulation training solution in the modern military field.a new issue.Based on this,this thesis will design and implement a radio simulation training system based on Unreal Engine 4.In this system,innovative functions such as terrain simulation,communication environment simulation,and result evaluation will be designed and implemented,thereby improving the reality of radio training.It provides a valuable idea and scheme for future military equipment simulation training.This thesis designs and implements a tactical Internet radio training simulation evaluation system based on Unreal Engine 4.The core functions are divided into two parts:simulation training and communication simulation.Starting from the core functions of the system,this thesis divides the system into five modules:1)Scenario building module,which is responsible for generating scenarios used for training and simulation,including terrain,weather types,communication equipment,etc.The random map generation function of the algorithm;2)Task imaging module,which is responsible for realizing the training simulation tasks that can be independently imagined in the scenarios generated by the scenario building module.The task types include path planning,selecting communication strategies,etc.The shortest path planning function of the A*pathfinding algorithm;3)Simulation training module,this module is mainly aimed at the core function of simulation training,and realizes the function of the trainer’s operation of the radio station under specific scenarios and tasks to achieve the purpose of training.And realize a variety of interfaces for realtime and non-real-time communication between the two core modules of training and simulation;4)Interference and anti-interference simulation module,this module uses OPNET simulation software to realize a variety of interference and anti-jamming models.The interference model includes Blocking interference,tracking interference,synchronization head interference,anti-jamming models include frequency hopping antijamming,communication feint anti-jamming,transceiving inter-frequency anti-jamming.In the process of training and simulation,these communication models will affect and improve the difficulty and authenticity of training,so as to achieve the purpose of tactical Internet simulation;5)Evaluation analysis module,which is an evaluation of the results of training and simulation in the above modules,the results that can be evaluated include statistics such as signal-to-noise ratio,bit error rate,and packet loss rate in the simulation,as well as indicators such as the correctness of radio operation and radio operation proficiency in training.The evaluation and analysis function based on AHP is designed and implemented to give feedback to the user’s training and simulation effects.At the end of this thesis,the two core functions of the system are tested for function and performance.The functional tests include random generation of maps,correct planning of the shortest path,combination of training radio and communication simulation,interference and antiinterference models,and analytic hierarchy process evaluation and analysis.The performance tests discussed and analyzed the Perlin noise algorithm used to generate the map and the A*pathfinding algorithm used to plan the path.The test results verified that the various modules of the system can work in coordination with each other,and confirmed the validity,reliability and accuracy of the results produced by using the system for training and simulation.Practical application guidance. |
