地形跟随/地形回避实时仿真系统的设计与实现

Design and Implementation of Terrain Following/Terrain Avoidance Real-time Simulation System

为了验证低空突防系统中的地形跟随/地形回避关键技术,设计了一套分布式实时仿真系统。该系统由主控机、地形跟随/地形回避(TF/TA)计算机和视景演示计算机组成。TF/TA计算机采用先进的嵌入式实时操作系统VxWorks进行TF/TA飞行轨迹规划,实时地形匹配,以及模拟雷达的实时数据生成。该系统可以验证算法,模拟飞机在空中飞行的实际效果,为TF/TA系统的试飞验证提供必要准备。

A real-time distributed simulation system is desigened in order to analyze and validate the key technology of Terrain Following/Terrain Avoidance（TF/TA） system. The simulation system consists of three computers： the host computer, the TF/TA embedded computer and the 3D showing computer. TF/TA computer implemented by VxWorks embedded real-time operating system can plan flight trajectory, match terrain and simulate radar data. The real-time simulation system can be used to verify TF/TA algorithm and simulate real flight effect.
