海上短波远程通信链路仿真预测

摘要

A short-wave telecommunication circuitry between maritime ship and shore receivers is analysed by ICECAP HF propagation software and the field intensity of the ship board antenna, SNR and MUF is simulated. On the basis of analysing the field intensity, the number of the receivers which the field intensity median is bigger than the valve of receiver, When the SNR is satisfied and the frequency is lower than MUF. It vilidly decribed the process of maritime short wave tele-communication.%采用ICECAP高频传输预测软件对海上舰船与岸基多台站之间的短波远距离通信电路进行仿真分析，计算了最高可用频率、信噪比和舰载鞭状天线的场强分布，分析了天线的场强覆盖，在满足信噪比的要求及频率低于MUF的条件下，计算出场强中值大于接收机灵敏度的台站个数，形象地描述了海上短波远程通信过程。
