VLF

频率非常低

Very low frequency

超低频或VLF是指3 kHz至30 kHz范围内的射频和10至100公里的波长。 由于无线频谱的该频带中没有太多的带宽,所以不能发送音频,并且仅使用低数据速率编码信号。 VLF频段用于几个无线电导航服务,政府时间广播电台广播时间信号来设置无线电时钟,并用于安全的军事通信。 由于VLF波进入海水约40米,因此用于与潜艇的军事通讯。 波长范围从1到10个,也被称为“无脊椎动物”(myriametre band or myriametre wave)。 Very low frequency or VLF refers to radio frequencies in the range of 3 kHz to 30 kHz and wavelengths from 10 to 100 kilometres. Since there is not much bandwidth in this band of the radio spectrum, audio cannot be transmitted, and only low data rate coded signals are used. The VLF band is used for a few radio navigation services, government time radio stations which broadcast time signals to set radio clocks, and for secure military communication. Since VLF waves penetrate about 40 meters into saltwater, they are used for military communication with submarines. Also known as the myriametre band or myriametre wave as the wavelengths range from one to ten myriametres.
