Radar Information Real-Time Simulator Based On Complex Electromagnetic Environment

雷达信息实时可视化是战场可视化的重要组成部分,对作战推演、评估有重要影响,建立了一套雷达信息实时仿真系统。该系统以实时变化的电磁环境为基础,考虑自然环境和动态电磁干扰,能够直观高效地展示雷达三维信息。首先通过扩展经典雷达方程,建立了基于雷达方向图函数和探测距离为参量的数学模型,以非均匀采样法绘制出了雷达三维威力范围。然后利用基于多种自然因素对雷达方程中的路径损耗的电磁传播衰减数学模型,实现了自然环境影响下的雷达信息可视化;运用雷达干扰方程,实现了单/多电子干扰情况下雷达信息可视化。根据基于参数的雷达绘制阈值变化的方法,提高绘制速度;最终利用基于网状数据的逻辑结构方法,实现了多部参战平台处于复杂电磁环境下相互干扰的雷达信息实时可视化系统。结果表明,该系统不仅观察效果真实直观,而且能动态、实时的可视化雷达信息系统。

Radar information real-time visualization is an important component of battleground visualization, and it has a deep influence on battle deduction and estimate. This paper constructs a system of radar information real-time simulator. This system can directly and with high-efficiency display radar 3D information, based on real-time change of electromagnetic environment, with natural environment and dynamic electromagnetic interference consid ered. To begin with, paint 3D radar detecting range with Non-Uniform Sampling method and modeling mathematics based on radar directional pattern and detecting range through expanding classic radar equation. Furthermore, we achieve radar information visualization under the influence of natural environment, by using mathematics model built by considering the effects of various environment factors on radar equation. We realize radar information visualization under the influence of simple/multi electronic interference through using Radar-Interference Equati We enhance the render refresh rate with utilizing LOD-control. Finally we achieve radar information real-time visualization system with multiple battle platforms, based on Network Data Logic method. The results and their analysis shows preliminarily that this system is not only lively but also can dynamically and timely visualize the radar information system.
