摘　　要：研究了罗兰C信号水下传播的各个场分量的特征,仿真计算了各个场分量的大小,重点分析了罗兰C电、磁场信号的水下传播深度随电路检测分辨率的变化规律,得出了利用磁天线水下接收罗兰C信号是实现水下定位导航的最佳选择的结论。以磁天线为基础,计算了磁天线水下感应罗兰C信号电压的大小,并进行了实测数据试验。结果表明,在表层水域(深度小于10m),利用磁天线水下接收罗兰C信号实现定位解算是可行的。The underwater propagation characteristics of Loran-C was researched and the H-field and E-field were calculated,and he result that the H-field antenna was the best way for receiving Loran-C signal underwater was obtained.The variances of the under-water propagation depth for H-field and E-field with the resolving power of circuits were analyzed.The voltage of H-field antenna influenced was calculated.Experiments indicate that position is feasible underwater（with the depth is less than 10m）with Loran-C signals received by H-field antenna.
