摘要:
针对战场级的复杂电磁环境仿真过程中涉及到全频段覆盖、环境影响、仿真速度要求高等问题,提出了一种综合考虑用频装备、环境信息和模型自身特点的电波传播模型选择方法。该方法首先通过频段对用频装备及电波传播模型进行划分,再结合环境信息中降雨量、海拔、植被覆盖率、气候类型、导电特性等参数进行综合分析,最终得到传播模型的优化选择方案。在典型作战场景仿真应用中,该方法为传播模型的合理选择提供了思路,保证了仿真的精度,同时也为电磁环境仿真中传播模型本地化提供了依据。

Abstract:
As for some problems such as full frequency band coverage,geographical environment,and high speed of simulation in the process of battlefield-class complex electromagnetic environment simulation,a radio wave propagation model comprehensive selection method is proposed based on frequency equipment,geographical environment information and the model itself.Firstly,this method divides the frequency spectrum equipment and the radio propagation model by frequency band.Then,it analyzes the parameters such as rainfall,altitude,vegetation coverage,climate type and conductive characteristics in the geographical environment.Finally,it obtains the optimal selection scheme of the propagation model.In the simulation application of the typical combat scene,this method provides not only a reasonable idea for the propagation model to ensure the accuracy of the simulation,but also the basis for the electromagnetic environment simulation in the dissemination of model localization.
