| Abstract(in English) | Our research group has researched about improving information speed and quality of broadband internet on maritime mobile satellite communications. In maritime mobile satellite communications, mechanically-controlled satellite tracing systems are used to compensate fluctuations of antenna orientation due to ship attitude caused by waves or winds of the sea. Orientations of antennas are limited so that transmitted electromagnetic waves from the antennas are not affected by structures on ships. Our research group studied about relation between separation angles and interference levels on other satellites by using a simple model or an actual ship model. The aim of this report is to develop a stochastic model of interferences on other satellites caused by diffracted waves by ship body. In this report, by employing a realistic ship model and directions of commercial satellites, a stochastic interference model is proposed. As a result, by using separation angles as a parameter, level of interference on other satellites can be estimated under the simulation conditions of this report. |
