摘要
论述了在罗兰C信号上实现数据通信的调制方法,采用PPM/IFM/SIM混合调制,可使罗兰C数据链的通信速率达到1kbps以上;通过罗兰C发射台发射调制信号,实现了罗兰C系统通信导航功能的一体化;罗兰C数据链可应用到多个方面,对提高系统的信息化水平具有重要作用.
The paper illustrate the way how to modulate Loran-C signal to realize data communication, use PPM/IFM/SIM modulation ,the Loran-C data link can obtain over 1kbps data rate. By means of modulate Loran-C signal in Loran-C transmitter, the Loran-C system can achieve communication and navigation at the same time ;Loran-C data link can apply to a great many use, it is significant to improve the army's information level.
