摘要
近海短波传播方式的确定具有现实意义。采用建模的方法,给出了地波场强计算模型和天波场强计算模型,采用举例的方法对地波与天波近海传播作了比较,得出了近海地波场强要强于相应的天波场强的结论,对正确认识近海短波传播方式有重要意义。
The determination of offshore short-wave propagation pattern has realistic meaning. Adopting modeling method, this paper puts forward ground wave and sky wave field-strength computational models,compares ground wave with sky wave propagation pattern in offing area by means of illustrating method, reaches a conclusion that ground wave field-strength is stronger than sky wave field-strength in offshore. This conclusion is of important meaning to precisely understand short-wave propagation pattern in offshore.
