摘要
战场环境是一个复杂、动态的信息空间,战场环境模型应能根据模拟需求,既反映战场环境的动态多变性,又具有一定的抽象性,减少计算量,满足实时性。为此以武器装备论证为仿真目的,分析了其战场环境模拟的需求,建立了关于地理环境的可视性和通行性模型、动态气象环境模型、电磁环境模型和目标运动特性模型,分析了作为仿真联邦组成的战场环境成员的内外部关系,采用基于推算定位算法(Dead Reckoning Algorithm,DR算法)的数据更新策略,调和了仿真精度和通信带宽的矛盾。
Battlefield environment is a complex and dynamic information space,based on simulation needs the models of battle environment should not only reflect its dynamic and changeableness but also have abstraction,less calculation and real-time.This paper analyses the requirements based on the demonstration of weapons and equipments in battlefield environment,presents some models for variablelity of battlefield,including inter-visibility model,traversability model,dynamic weather model,electromagnetic environment model and moving targets model.Finally,this paper analyses battlefield member＇s internal and external relations,presents update strategy based on dead reckoning（DR） algorithm to make simulation precision and communication bandwidth consistent.
