中文摘要：

介绍了罗兰C磁天线的硬件构成方框图及其工作流程．并通过外场试验，从信噪比、时差稳定性及失锁情况三方面验证了磁天线的性能优于电天线。罗兰C磁天线相对于电天线更有利于接收罗兰C信号，抑制干扰，提高信噪比，获得较高的时差测量精度，对台链各台发射信号的时间基准的调整更准确，获得更可靠的定位结果。提高了定位系统的利用率。

英文摘要：

The frame charts of hardware structure and work flow of Loran-C magnetic antenna were introduced. It is val- idated that magnetic antenna is better than electric antenna in the aspects of SNR, stability of time difference and unlocked circumstance via outfield experiment. Compared with electric antenna, the magnetic antenna does well in receiv- ing Loran-C signal, restraining disturbance, advancing SNR, achieving higher precision of time difference measuring,so the time reference can be adjusted more accurately, more reliable positioning result can be obtained and the utilization rate of positioning system is improved.
