摘要
通过分析Alpha甚低频信号空气—海水跨介质及水下传播规律,重点研究了影响水下磁场天线接收性能的主要噪声源,并给出相应解决措施,提出了甚低频磁场接收天线的设计方案,经测试验证具备水下20 m接收甚低频导航信号的能力和可行性。
According to analyze air-sea water cross medium and underwater propagation law of alpha VLF signal,focuses on the main noise sources affecting the receiving performance of underwater magnetic antenna,gives the corresponding solutions,and puts forward the design scheme of VLF magnetic receiving antenna.The test shows that it has the ability and feasibility of receiving VLF navigation signal 20 meters below water.
