tracking range

In April-November, 2003, a preliminary study on the home range of Chinese Alligator was conducted by radio tracking 3 released captive Chinese Alligator.

2003年4月&11月，使用无线电遥测设备对释放到野外的3条扬子鳄进行跟踪实验；

In this paper, a new type of flight follower designed and realized in the background of the optical tracking and measuring of moving target in shooting range.

本文以靶场运动目标如炮弹、导弹等的光学跟踪测量为背景，设计实现了一种新型反射跟踪器。

With optimal design and processing. a 10-bit precision is achieved without laser trimming and good temperature tracking property is obtained in full temperature range (-55~ 125 ℃).

在设计和制作上进行优化，不用激光修调能够达到10位精度，在全温范围内有较高的温度跟踪特性。

The problem of detection and tracking of dim point target comes from application of long-range surveillance system, such as wide FOV ( field of view) telescope and SBIRS ( Space-based infrared system) and other surveillance system.

能见度低的点源目标的检测和跟踪问题产生于远程监控的应用背景中，比如宽视场望远镜，红外搜索和跟踪系统以及其他基于点源目标检测的监控系统。

The scheme accomplishes range tracking by adopting three range gate tracking to make middle gate always centered at echo pulse center through feedback circuit and deviation calculation circuit.

该方案采用三波门跟踪，通过偏差计算电路和反馈控制电路使中间波门中心始终对准目标回波脉冲中心，完成距离跟踪。

Long Range Ultra Short Baseline orientation system is required to achieve five underwater targets positioning, tracking and data communicating, for example AUV and UUV etc, and its best positioning precision of incline distance is less than 5 ‰.

长程超短基线定位系统要求实现对水下4千米海深的5个目标，如AUV、UUV等进行定位、跟踪和数据传输，最佳定位精度达到千分之五斜距。
