短波天波通信链路计算模型研究

为建立远程舰艇短波通信可靠通信链路,简化短波通信工程中天线和通信台站设计过程,研究设计了一个完整的短波通信链路计算模型。该模型包含天线辐射特性计算模型、短波通信电路计算模型、短波天线数据库和通信链路地理参数数据库四大部分。在此基础上,使用该模型进行了实例分析,确定了在一定条件下的工作频率、反射模式,预估场强强度,为短波天波通信工程设计提供依据。

Study on Calculation Model for HF Sky Wave Communication Link

For establishment of reliable short-wave communication link for long-distance ships and reduction of the antennas and stations design process in short wave communication project,a calculation model for short wave communication links is designed,which consists of calculation models for antenna radiation,HF communication circuit,short-wave antenna database,and geographical parameters database in communication links.An example is analyzed with this model,thus to establish the working frequencies,reflection mode and predicted field strength,and to provide a basis for short wave communication engineering design.
