摘　　要：巡航导弹飞行模拟实时仿真系统以VC++ 为开发平台,VEGA视景仿真软件作仿真引擎,选用MultiGen Creator建立导弹实体仿真模型及场景地形模型库,同时将场景数据库地形数据转换成vrml格式供主控制模块调用地形匹配算法。仿真应用中,将地形表面三角离散化形成仿真场景模型,利用地形模型的高程数据,动态改变仿真循环中巡航导弹的方位、姿态等特征,模拟实现巡航导弹飞行过程中的地形匹配。Virtual real-time simulation system for flight of cruise missile was developed with VC++. VEGA acts as emulation engine, entity simulation model of cruise missile and scene topographical model base set up with MultiGen Creator. At one time, the topographical data in scene database was converted into vrml file to transfer terrain matching arithmetic for host control module. In simulation, triangles of topographical surfaces are dispersed to form the simulation scene model. The position and posture characteristics of the cruising missile in simulation circulation was changed dynamically with the altitude data of topographical model, and the terrain matching simulation of flying process for the cruise missile was realized.
