对VLF相位周期丢失的分析

本文分析了在新乡、兰州两地接收Omega导航系统G台的信号。结果表明,测出的相让周期丢失是VLP远距离传播所具有的传播现象。同时,结合在兰州的测试结果,进一步分析了产生这种传播现象的原因。 

ANALYSIS OF VLF PHASE CYCLE LOSS

The paper analyses the data of received Omega Signals from G station, at Xinxiang and Lanzhou respectively. It is worth especially noting that two receivers, which are adjusted in the optimum operating conditions, are used to simultaneously receive the signals at Xinxiang.The experimental results show that the measured phase cycle loss is a kind of propagation phenomenon during VLF signal travelling. And together with the measurement result at Lanzhou, the reason for this phenomenon may be analysed forther.
