RADIO DIRECTION FINDING在英语中的意思是什么？

方向发现

Direction finding

指向查找或无线电测向是指接收信号发送方向的测量。 这可以指无线电或其他形式的无线通信。 通过组合来自两个或更多个适当间隔的接收器的方向信息，变速器的源可以通过三角测量位于空间中。 无线电方向发现用于船舶和飞机的导航，定位搜索和救援应急发射机，跟踪野生动物和定位非法或干扰发射机。 RDF系统可以与任何无线电源一起使用，尽管接收机天线的尺寸是信号波长的函数 - 非常长的波长需要非常大的天线，并且通常仅用于基于地面的系统。 然而，这些波长对于海洋无线电导航非常有用，因为它们可以在“地平线”上行驶非常长的距离，这对于船只在视线可能只有几十公里时是有价值的。 对于空中使用，地平线可以延伸到数百公里，可以使用更高的频率，允许使用更小的天线。

Direction finding, or radio direction finding, refers to the measurement of the direction from which a received signal was transmitted. This can refer to radio or other forms of wireless communication. By combining the direction information from two or more suitably spaced receivers, the source of a transmission may be located in space via triangulation. Radio direction finding is used in the navigation of ships and aircraft, to locate emergency transmitters for search and rescue, for tracking wildlife, and to locate illegal or interfering transmitters. RDF systems can be used with any radio source, although the size of the receiver antennas are a function of the wavelength of the signal - very long wavelengths require very large antennas, and are generally used only on ground-based systems. These wavelengths are nevertheless very useful for marine radio navigation as they can travel very long distances "over the horizon", which is valuable for ships when the line-of-sight may be only a few tens of kilometres. For aerial use, where the horizon may extend to hundreds of kilometres, higher frequencies can be used, allowing the use of much smaller antennas.
