基于ITS软件的短波频率管理系统设计

美国ITS(Institute for Telecommunication Sciences)组织开发的短波中长期频率预测软件在全球范围内应用非常广泛。通过学习该预测软件的工作原理和模式,结合大区域网络化应急短波通信的频率管理需求,设计开发了具有MUF(MaximumUsable Frequency)频率预测、ALE(Automatic Link Estab-lishment)扫描频率预测、频率覆盖预测、台站选址预测、工作频率性能预测等5种功能的短波频率管理系统,该系统可结合各种探测数据进行频率规划和动态调整。实际应用表明,该系统可极大改善和提高短波通信链路的选频质量。

Design of an HF frequency management system based on ITS software

The HF medium and long term frequency prediction software developed by the Ins titute for Telecommunication Sciences(ITS) of the USA has been widely used all over the world.By studying the working principle and working model of th e software, combined with the large regional networked emergency HF communicatio n frequency management requirements,an HF communication frequency ma nagement system with five functions based on the ITS software is designed such a s MUF(Maximum Usable Frequency) frequency forecast,ALE(Automatic Link Establishm ent) scanning frequency forecast,frequency coverage forecast,station locatio n forecast,work frequency performance forecast. This system can combine all sort s of detection data to plan the frequency and realize the dynamic adjustment.App lication demonstrates it can greatly improve and enhance the quality of HF commu nication link when choosing frequency.
