rf data link
Examples with "rf data link" and their translation in Chinees
An RF data link has the advantage of allowing the AV to fly free of any physical tether to the control station.
射频数据链路的优势在于飞行器不受控制站线缆拴系的物理限制。
Most UAV systems will use an RF data link.
大部分无人机系统使用的是射频数据链路。
The MSP-TRF6903-DEMO Kit is used to demonstrate a bidirectional RF data link without the need of an external computer and for prototyping by downloading new software code to the MSP430F449 through the JTAG connector. The schematics and layout of the board can be used as a reference design if desired.
MSP-TRF6903 演示套件用于演示双向射频数据链路，无需外部计算机，用于原型开发，通过 JTAG 连接器将新的软件代码下载到 MSP430F449 中。如果需要，可以使用该板的示意图和布局作为参考设计。

If long distances are involved, high-bandwidth RF data links may be used, with their own special requirements for antennas and RF systems.
如果涉及的距离遥远，就可以使用高带宽的射频数据链路，连同其自身对天线及射频系统的特殊需求也一并考虑。
The functions of a data link are the same regardless of how it is implemented, but we concentrate in this textbook on issues that apply to RF data links.
不管以何种方式实现，各种数据链路的功能是基本一致的，不过本书将集中讨论适用于射频数据链路的问题。
from the MPCS LAN to a data-link interface within the MPCS shelter; (2) from the shelter-mounted part of the data link to the modem, radio frequency (RF), and antenna parts of the data link at a remote site; (3) from the data-link transmitter via the RF transmission to a data-link RF and modem section in the AV (the air data terminal); and finally (4) from the modem in the AV to the air vehicle LAN.
方舱内从任务规划和控制站局域网到数据链路的接口；②从数据链路安装在方舱的部分到数据链路在遥测站点的调制解调器、射频（RF）和天线部分；③从使用射频传输系统的数据链路发射机到飞行器上的数据链路射频和调制解调器部分（机载数据终端）；④从飞行器上的调制解调器到飞行器局域网。
A data link may use either a radio-frequency (RF) transmission or a fiber-optic cable.
数据链路可运用射频（RF）或光缆进行数据传送。
There can be a corresponding advantage against unintentional interference if the interfering source is operating at a single frequency, which is typical of the ordinary kinds of radiating RF sources that may interfere with a data link.
若干扰源 使用单一频率工作，这种增益应对无意干扰具有特有的优势。 对可干扰数据链路的辐射性射频源而言，这是一种典型的情况。
Frequency-hopping data links may be less expensive, for equivalent processing gain, than direct spread-spectrum links because the switching rate to frequency hop is much lower than the modulation rate for direct spreading and the instantaneous RF bandwidth required is much lower.
由于频率跳变的切换速率比直接扩频调制速率要低得多，且所需射频瞬时带宽也窄很多，在相同处理增益，跳频数据链路要比直接扩频数据链路价格会更低一些。
The common data link could, by definition, be interoperable and interchangeable between systems since it would hardly qualify as common unless all versions used the same RF sections and modems, at least through conversion of the signals from or to digital data in an input or output buffer.
根据定义，通用数据链路应在系统间具有互操作性和互换性，因为如果所有版本不是采用相同射频区段和调制解调器的话，是很难被认定为通用的，至少也要在输入或输出缓存中完成信号和数字数据间的相互转换。
If, on the other hand, the data link had to operate in a non-line-of-sight mode at long range with omnidirectional antennas, it would need 40 dB of processing gain, resulting in a 100-GHz transmitted bandwidth, which is not possible at any frequency that can propagate non-line-ofsight. (In fact, it would not be possible at any frequency for which traditional RF technology applies.)
另一方面，假定数据链路必须按非视距传播模式工作，且采用全向天线进行长距离传输，那么，该数据链路将需要40dB处理增益及100GHz传输带宽，这在任何能进行非视距传播的频率上都是不可能实现的（实际上，这在传统射频技术采用的任何频率上也是不能实现的）。
The equipment on the ground is called a ground data terminal (GDT) and consists of one or more antennas, an RF receiver and transmitter, modems, and processors to reconstruct the sensor data if it has been compressed before transmission. (The question of whether data compression and reconstruction should be internal or external to the data link is discussed later.)
数据链路的地面设备也称地面数据终端（GDT），该终端包括一副或几副天线、一台射频接收机和发射机、调制解调器。 若传感器数据在传送前经过压缩，则地面数据终端还需采用处理器对数据进行解压（数据压缩和解压应该设计在数据链路内部还是外部，这个问题将在后面的内容予以讨论）。
