战场区域地形隐蔽性分析

Analysis of Terrain Invisibility in Battlefield

为获取战场地形隐蔽性信息,按照作战行动空间划分,将区域地形隐蔽性分为:对地隐蔽性,以区域内山顶点为视点;对空隐蔽性,以区域上空规则离散点为视点。区域地形隐蔽性分析,引入视点隐蔽域和地形点隐蔽性,对参考面算法进行适用性改造,将区域地形隐蔽性和地形隐蔽性面作为分析结果。实验表明,该方法能够客观反映目标地形区域的地貌基本分布情况和区域整体地形隐蔽性大小,可用于不同区域间的地形隐蔽性对比。

In order to obtain terrain invisibility in battlefield, according to the division of operational space, area terrain invisibility can be divided into two parts: invisibility based on ground which peaks in the area are considered as viewpoints, and invisibility based on sky which regular discrete points over the area are considered as viewpoints. Shielding area of viewpoint and invisibility of topographic point are introduced into analysis of area terrain invisibility. The reference planes algorithm is reformed so that it can be used in analysis. The value of area’s terrain invisibility and the surface of terrain invisibility are two formats of analysis results. Experiment shows that the method can objectively reflect geomorphic distribution and terrain invisibility in area, and can be used for comparison of different areas’ terrain invisibility.
