摘要
针对电磁对抗领域中电磁态势显示的需求及传统电磁传播模型计算速度慢的现状,提出了一种基于粒子系统的电磁场强计算及显示方法。将基于电磁波传播模型的辐射源空间电磁场强计算简化为基于粒子系统的图形计算及显示方法,针对辐射源工作参数及天线方向图数据生成OSG粒子模型,利用OSG引擎的高速计算及渲染能力,直接将计算结果渲染至二维/三维态势图中,实现了在复杂电磁环境下电磁态势的实时显示。
To satisfy the requirement for electromagnetic situation display and improve the calculation speed of electromagnetic field intensity distribution in the field of electromagnetic countermeasure, the paper discuses a new calculation method,which replaces the traditional electromagnetic propagation calculation with OSG particle system modelling.By modelling OSG particle with parameters of radiation source and antenna pattern data,and through the high calculation capability of GPU,this method directly turn the results into electromagnetic situation, which guarantees the real-time display of electromagnetic situation in complex electromagnetic environment.
