2) terrain following
地形跟踪
1.
The optimization flight path based on terrain following;
一种基于地形跟踪的航迹优化算法
2.
Applying the theory of singular perturbations,this paper adopts an aerodynamic missile layered control algorithm to divide a terrain following system into the velocity layer,attitude angles layer and angular velocities layer.
根据奇异摄动理论,采用飞航导弹的分层控制方法,将地形跟踪控制系统分成速度、姿态角和角速度三部分,提出了一种利用动态逆滑模控制进行飞航导弹地形跟踪控制器的设计方法,同时充分考虑了导弹系统中的不确定性误差,保证了系统误差收敛。
3.
This paper presents an optical forward vision system based on adaptive angle method for the high accuracy height measurement problem of cruise missile s terrain following,which can reduce the traditional altimeter method s flight height measurement error.
针对某巡航导弹地形跟踪的高精度测高问题,文中采用适应角法的光学前视系统,以减少传统高度表法的飞行高度测量误差。
3) ground target tracking
对地跟踪
1.
Research on general ground target tracking based on terrain information;
利用地理信息的广义对地跟踪研究
2.
Through introducing terrain information, the ground target tracking may be further improved because the constraints of the terrain information can decrease the target modeling uncertainties due to unexpected maneuvers.
因而有助于提高对地跟踪性能。
