摘要
针对海上实际通信环境,分析了海上短波传播方式及影响短波传输信道特性的参数,结合鞭天线方向图,对近场和远场的地波和天波场强进行了计算和对比分析,并得出结论,为海上短波有效通信提供了理论依据。
Based on the communication environment at sea,the transit methods and parameters which influence transmit characteristic of HF transmission Channel.Combined with the whip antenna power rating,the ground-wave field-strength and the sky-wave field-strength are alculated and compared.The conclusion provides theory evidence to establish available communication at sea effectively.
