Research on Terrain Visibility Analysis Model of Radar Detection Range

雷达探测目标时,受地形复杂程度影响很大,加上地球曲率的影响,会产生很多探测盲区,通过研究分析雷达探测区,既可以进行突防、突击,又可以对雷达进行优化部署,减少雷达探测的盲区。为了获取高效、准确的雷达探测范围,本文在研究相关领域现有成果的基础上,结合雷达探测原理和特点,并且顾及了无线电波在空气中传播折射的影响而引入了等效地球半径,提出了以等效地球半径为基准的雷达探测范围地形可视域分析方法。该方法包括基于地形分析的可视域分析原理算法和建立在地理信息系统基础上的可视域分析数学模型。本文还给出了该模型的算法与实现,并对结果进行了分析和评估。

Due to terrain complexity and the influence of earth curvature, many blind detection areas will be generated. In order to reduce the blind detection area obtain the range of radar detection area efficiently and accurately, taking the principles and characteristics of radar detection and refraction influence of radio waves into consideration. This paper proposes a terrain visibitity analysis model based on the existing achievements in related areas. The method includes the algorithm based on terrain visibility analysis principles and the Geographic Information System-based mathematical model for visibility analysis. In addition, the algorithm and implementation of the model are also provided in this paper, and the results are analyzed and evaluated.
