摘要
由于电磁环境的复杂性,较难具体、完整地显示区域中的电磁环境,难以用一个普遍适用的准确算法来进行可视化。本文系统采用快速电磁传播计算方法或插值方法,完成任务场景中各辐射源的电波传播、覆盖、干扰效果计算和电磁频谱占用情况显示。通过对空间电磁环境中的地形与电磁数据进行统一建模、解析并作可视化映射,从多个维度对电磁场进行可视化处理,实现了电磁分布态势、等值线、传播方向路径等多种形式的电磁环境的态势显示。综合考虑不同频率、传播路径、天线形式和地形地貌等参数对战场电磁环境分布的影响,实现电磁传播和覆盖效果计算与显示,形成综合电磁态势效果并利用区间映射的办法。
Because of the complexity of electromagnetic environment,displaying the electromagnetic environment inside an area in details and completely is extremely difficult,and finding a universally applicable algorithm with high accuracy for the visualization is also a huge challenge.In our system,fast electromagnetic propagation calculation method or interpolation method is adopted to complete the calculation of radio wave propagation,coverage and interference effect as well as the display of electromagnetic spectrum occupancy of all radiation sources in the task scenes.By unified modeling,analyzing and visual mapping the terrain and electromagnetic data in the spatial electromagnetic environment,visualization processing of the electromagnetic field is carried out from multiple dimensions,and the display of the electromagnetic environment is realized in various forms including distribution state,contour line,propagation direction path,etc.To realize the calculation and the display of electromagnetic propagation and coverage effect,and to form a comprehensive electromagnetic situation effect as well as to utilize the interval mapping method,the influence of different frequency,propagation path,antenna form and terrain on the electromagnetic environment distribution of the battlefield is comprehensively considered.
