Abstract

In order to effectively improve China’s maritime communication service and maritime traffic safety guarantee capability, a MF/HF coastal radio station coverage model based on terrain feature factor was proposed by analyzing maritime MF/HF signal propagation model and combining with the terrain features of radio coverage area. On this basis, the distribution scheme of MF/HF coastal radio stations such as distress safety communication, maritime safety information broadcasting and high frequency conventional communication was designed. The distribution scheme fully integrated the modern development needs of GMDSS and incorporated the new digital broadcasting technology of NAVDAT. The coverage effect of the distribution scheme was simulated and verified based on the topographic distribution and coverage model of MF/HF coastal radio. The results show that the design of MF/HF coastal radio distribution scheme can achieve seamless coverage of China’s coastal waters, and optimize the operational efficiency of China’s coastal radio.
