摘要
为了在体系级对抗仿真中有效平衡通信系统建模的精细度和实时性的问题,提出一种面向对抗仿真的通信系统多粒度建模方法,构建了军事通信系统工程级、功能级和任务级模型。对于精细度要求较高的场景,利用专业电磁仿真软件离线解算通信设备的天线数据,并在仿真运行中在线插值从而实时得到准确的数据。对于仿真实体较多的应用场景,采用典型参数来简化描述天线的方向性。对于大规模的军事通信网络,模拟实体运动带来的通信覆盖范围变化情况。在建模过程中考虑了战场通信干扰、大气环境干扰以及地形通视性的计算情况,建立一套从天线解算、链路仿真到军事通信网络的多粒度模型,来支撑体系级对抗仿真。
Aiming at the problem of effectively balancing the precision and real-time of communication system modeling in system level confrontation simulation,a multi-granularity modeling method of communication system for confrontation simulation is proposed,and the military communication system is modeled at engineering level,function level and task level respectively.For scenes with high precision requirements,professional electromagnetic simulation software is used to solve the antenna data of communication equipment offline,and online interpolation is used during simulation operation to obtain accurate data in real time.For the application scenarios with many simulation entities,typical parameters are simplified to describe the directivity of the antenna.For large-scale military communication networks,the changes of communication coverage caused by physical movement are simulated.In the modeling process,the calculation of battlefield communication interference,atmospheric and terrain visibility is considered,and a set of multi-granularity models from antenna solution,link simulation to military network communication are established to support system level confrontation simulation.
