摘　　要：传统的飞行器地形跟随飞行主要依赖前视地形跟随雷达来确定航线周围的地形轮廓,实现地形跟随;基于DEM高程数据和机载控制计算机,提出一种新的飞行器实现无源地形跟随技术的技术途径、系统方案和可能出现的关键技术,并对涉及的主要关键技术实现进行了分析和讨论;关键技术包括导航曲线生成系统的实现方法和技术途径,执行地形跟随飞行控制的机载计算机基本需求、系统结构和设计方法等;经过仿真验证,按照该方法的控制的跟随飞行在高程和飞行姿态方面满足预计目标。Abstract： The subsistent systems of terrain--following for vehicle flight require forward looking airborne radar {or ascertaining terrain profile around the flight line commonly. There presents an approach for passive terrain--following of vehicle flight based on Digital Elevation Model （DEM） and Airborne Control Computer. With this approach we supply a formal methodology for the design, implemetation and vali- dation of reactive systems, and evaluation about the crucial technique which include the implemetation of the navigation curve created system, and the basic requirement, system architecture and software design function of the airborne computer for terrain--following flight control cal- culating. Through simulation, the elevation and attitude meet the expected design target in accordance with the method of terrain--following flight.
