Ray Tracing Based Wireless Channel Modeling over the Sea Surface near Diaoyu Islands

Marine wireless channel modeling is significant to construct a maritime communication system. Three dimensional contour data of Diaoyu Islands is collected and analyzed. Then a three dimensional scene combined with sea surface is rebuilt through Matlab. Ray tracing based on angle searching and the deterministic channel modeling are used to model the wireless channels of the main scenes by air platforms(Unmanned Aerial Vehicle (UAV) or hot-air balloons) which carrying the wireless transceivers. A simulation considering relevant parameters like path loss, time delay and arrival angle are carried out. The results show that the pass loss is interrelated with the rough sea surface which also lead to an uncertain multipath effect.
