摘　　要：介绍了一种新型的利用甚低频电磁波进行水雷遥控的方案;利用甚低频的衰减特性,计算出在距发射点约400km处的辐射电场的场强,分析了在水下15m处与30m处的近似场强,根据得到的数据得出了甚低频遥控水雷设计的可行性;在此基础上,进一步论述了用FSK进行数字调制的系统设计方案,详细描述了遥控发射机与接收机的设计方法,水雷的分区编解码原理以及发射与接收天线的设计。A new design of naval mine is studied, which is remote-controlled by the very low frequency electromagnetic wave. We figure out the electric field＇s Field Intensity at the point of 400 kin, from the emission place, and analyses the approximate value of the Field Intensity of 15 meter department and 30 meter department under the water, according to the data, the design of the remote-controlled naval mine is feasible. Furthermore, the system design scheme about the digital modulation with FSK is discussed, design method of the remote transmitter and the receiver, the coding-decoding theory of the naval mines in the different districts, and the design of the transmitter and the receiver antenna are elaborated.
