摘要
短波表面波通信装备在通信应用中起着重要作用,特别是在海上通信中应用比较广泛。传输衰减情况一般根据国际无线电咨询委员会(CCIR)推荐的曲线进行计算,但有时计算值与实际使用情况存在一定差异,有必要进行短波海面波传输衰减的测量。介绍了短波海面波传输衰减的测量方法,结合实际分析选择了可行的测量方案,给出了测量结果,并对测量结果进行了分析。
The HF communication equipment using surface wave for communication play an important role in the communication application,especially it has a wide application in maritime communication. In order to obtain its transmission attenuation, we commonly use curve proposed by CCIR＇s for calculation. But sometimes its result is different from the practical use result, so it is necessary to measure the transmission attenuation of ocean surface wave. Firstly this paper introduces the method to measure the transmission attenuation of ocean surface wave, then chooses a viable scheme by analyzing practical use. Finally it gives and analyzes the measured result.
