摘要
为了模拟低空突防中飞行器面临的武器威胁、地形环境和大气环境等情况,需要建立一套完整的战场模拟仿真平台。在仿真平台结构分析的基础上,研究了低空条件下的威胁模型和环境模型,其中,着重描述了武器威胁各因素的自身特性,讨论了几种威胁形式的计算方法,提出利用地形组合、地形拼接的方法来处理地形数据以形成需要的战场地形,还考虑了大气环境对低空飞行的影响,最后结合实例说明生成的虚拟战场数据可以作为背景数据提供给低空突防航迹规划和导航、控制。
In order to simulate the threat of the weapons, terrain and atmosphere environment in low penetration, a simulation platform should be established. Based on the analysis of platform framework, the terrain model and threat model in low-attitude were studied. Especially, the characters of all weapon threat were described, and the calculation methods of several threat formats were discussed. The requisite terrain can be derived from the processing of terrain data by the combination and juncture of terrain. The effect of the atmosphere environment upon the flight in low altitude was taken into account. In the end, an example illustrates that the visual battlefield from the simulation platform can be taken as the background for trajectory planning, navigation and control.
