摘要

研究最大传输距离下的最小损耗和无线电传播在船舶导航中的实用性是一个永恒的课题。讨论了将传输损耗除以中值介质衰减和介质衰减校正系数。介绍并改进了朗利-赖斯模型;计算出了模型的相关比例。然后计算静浪条件下的反射校正系数，得到第一次反射的总损耗和强度。解释了信噪比，探讨了不同入射角与校正系数之间的关系。根据固定的信噪比14，得到了最高的弹跳频率。

A Mathematical Model of Multi-Hop HF Radio Propagation

It is an eternal topic to study the minimum loss under the maximum transmission distance and the practicality of radio propagation in the navigation of ships. The transmission loss by dividing it to Median medium attenuation and Media attenuation correction factor is discussed. The Longley-Rice Model is introduced and improved; the correlation proportion of our model is work out. Then the reflection correction factor is calculated in the case of silent and turbulent ocean, which comes to the total loss and strength of the first reflection. The signal to noise ratio is explained and the relationship between various angle of incidence and correction factor are explored. According to fixed signal to noise ratio 14, the highest bounce frequency is got.

期刊介绍： Applied Mathematics promotes the integration of mathematics with other scientific disciplines, expanding its fields of study and promoting the development of relevant interdisciplinary subjects. The journal mainly publishes original research papers that apply mathematical concepts, theories and methods to other subjects such as physics, chemistry, biology, information science, energy, environmental science, economics, and finance. In addition, it also reports the latest developments and trends in which mathematics interacts with other disciplines. Readers include professors and students, professionals in applied mathematics, and engineers at research institutes and in industry. Applied Mathematics - A Journal of Chinese Universities has been an English-language quarterly since 1993. The English edition, abbreviated as Series B, has different contents than this Chinese edition, Series A.
