track elevation

The paper discusses the capacity of the single observer in a T/ R-R type bistatic system without elevation message to locate and track moving targets in three dimensional space.

文中讨论了T／R&R型双基地系统中无俯仰信息收站对运动目标的三维定位跟踪能力；

Acquisition parameters ( including track direction, elevation and position control)

采集参数（包括航迹方向、高程和位置控制）

The track up to this time had reached its highest elevation at the Great Salt Lake.

这条铁路铺到大咸湖时已经达到了全线标高的顶点。

Among them, an outdoor test track inspection apparatus includes rail inspection instrument measured the orbital plane coordinates, track top elevation, gauge, level, track direction, height and distortions state track geometry parameters.

其中，轨检仪室外检测内容包括轨检仪实测轨道平面坐标、轨顶高程、轨距、水平、轨向、高低及扭曲等轨道几何状态参数。

The paper utilizes the non-linear dynamic theory of rolling stock running on the curved-track to research the safety and stability when the rolling stock running on the track overlapped elevation curve on the spiral curve.

用机车车辆曲线通过非线性动态理论，研究竖曲线与平面缓和曲线重叠对机车车辆曲线通过时的安全性和平稳性的影响。
