基于数字孪生的导弹部队在线仿真系统设计

Design of Online Simulation System for Missile Forces Based on Digital Twin

导弹作战具有复杂多变、不确定性强的特点,基于数字孪生技术在仿真系统中生成与现实世界实时同步的虚拟战场态势,从而进行作战方案在线仿真推演和效能评估,根据仿真评估结果预测战争走向,实现战场“透视”的目的,这对于指挥员掌握战场主动权和科学决策具有重要作用。通过建立在线仿真系统总体框架和内外部接口关系,将系统根据功能划分为战场情报预处理、实体模型动态生成与匹配、仿真推演、效能评估、仿真引擎和仿真支撑库等6个子系统,对各子系统的功能组成和运行机理进行解析,对基于EATI的建模法则和战场态势特征提取及模型匹配2项关键技术的具体原理和实现方法进行了解析,结合导弹部队的作战特点,建立了作战效能仿真评估指标体系,为下一步仿真系统的实现提供了方法指引。

Missile operations are complex,changeable,and highly uncertain.Based on the digital twin technology,a virtual battlefield situation that is synchronized with the real world in real time is generated in the simulation system,so as to conduct online simulation deduction and effectiveness evaluation of the combat plan,and predict the war according to the simulation evaluation results,and achieve the goal of"perspective"of the battlefield.This plays an important role for the commanders to master the initiative of the battlefield and scientific decision-making.By establishing the overall framework of the online simulation system and the relationship between internal and external interfaces,the system is divided into six subsystems,including battlefield intelligence preprocessing,dynamic generation and matching of entity models,simulation deduction,performance evaluation,simulation engine and simulation support library.The functional composition and operation mechanism of the subsystems are analyzed,and the specific principles and implementation methods of two key technologies,namely EATI-based modeling rule and battlefield situation feature extraction and model matching,are analyzed.Combined with the combat characteristics of the missile force,a combat performance simulation evaluation index system is established to provide a method guide for the realization of the next simulation system.
