摘要
雷达探测威力范围会受到多种环境因素的影响,如何在三维地理信息系统上展现雷达探测范围已成为研究热点之一。文章首先在理想情况下对雷达的探测范围进行理论分析,基于雷达方程推导出计算雷达威力范围的数学模型。然后分析地形遮蔽、电磁干扰和目标RCS等因素对雷达探测威力范围的影响,针对不同因素的影响对雷达探测范围的计算模型进行修正。最后在三维地理信息系统上绘制出雷达在受地形遮蔽、电磁干扰和目标RCS等复杂环境影响下的三维探测威力图,整个雷达威力图由遮蔽区、盲区和探测区组成。同时绘制出不同高度层的雷达探测威力范围,有助于决策人员对雷达探测威力直观研判。
The range of radar detection power is affected by many environmental factors. How to display radar detection range in 3 D GIS has become one of the research hotspots. Firstly, the detection range of radar is theoretically analyzed in an ideal situation, and the mathematical model for calculating the radar power range is derived based on the radar equation. Then, the influence of terrain shelter, electromagnetic interference and target RCS on radar detection range is analyzed, and the calculation model of radar detection range is modified according to the influence of different factors. Finally, the 3 D detection power map of radar is showed on the 3 D GIS under the influence of complex environment such as terrain masking, electromagnetic interference and target RCS. The whole radar power map is composed of shadowing area, blind area and detection area. At the same time, the range of radar detection power at different altitudes is drawn, which is helpful for decision makers to intuitively study and judge the radar detection power.
