Abstract
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.
