基于三维地球场景的干扰条件雷达探测范围可视化方法

雷达探测范围的三维可视化是现代战场电磁态势显示的关键组成部分。以电子对抗情况中雷达探测范围模型为基础，深入研究雷达局部坐标与地心直角坐标的转换算法，提出一种基于三维地球场景绘制理想条件与干扰条件下雷达探测范围的可视化方法。研究设计基于理想条件与干扰条件下雷达探测范围可视化数据需求的数据库，并基于三维地球场景平台ArcGlobe，结合OpenGL绘图技术，应用该可视化方法开发海战场电磁态势显示系统。实验结果表明该可视化方法能够高效形象地在三维地球场景下展现理想条件与干扰条件下的雷达探测范围，为指挥员洞察战场态势提供支持。

Visualization of Radar Detection Range Based on 3D Earth Scene Under Interference Condition

The 3D visualization of radar detection range is the key component of the display of modern battlefield electromagnetic situation. This paper puts forward a visualization method of radar detection range drawing based on the 3D earth scene. The method is based on the model of radar detection range in electronic countermeasures under ideal conditions and interference conditions, and combines with the coordinates transformation method between the geodetic coordinate system and geocentric coordinate system. By studying and designing a database based on the visualization data requirements of radar detection range under ideal conditions and interference conditions, based on the 3D earth scene platform ArcGlobe and OpenGL technology, we apply the visualization method to develop the marine battlefield electromagnetic situation display system. The experimental results show that the visualization method can accurately and vividly show the radar detection range in 3D earth scene under ideal conditions and interference conditions, and provide support for commanders to insight into the battlefield situation.
