海上对流层微波超视距传播与海洋大气环境特性相关性研究

海上对流层微波超视距传播与海洋大气环境特性的相关性研究对电波传播的短期预测以及无线电通信系统的设计和应用有着十分重要的意义。该文根据在我国黄渤海海域进行的14.1 GHz海上对流层微波超视距传播试验的传输损耗数据以及在发射端塔基平台上同步进行的气象梯度仪试验的气象数据，分别分析了风向、风速以及气海温差对传输损耗和蒸发波导高度相关性的影响，研究了沿海海域气象数据在微波超视距传播链路中的可用性，并结合散射抛物方程方法和高级折射效应预报系统(AREPS)对分析结果进行了验证。该文的研究结果对海上对流层微波超视距传播的传播特性以及短期预测的研究有一定的指导意义。

Study on the Relativities of the Tropospheric Microwave Trans-horizon Propagation above Ocean Surface and the Marine Atmospheric Environment Characteristics

Study on the relativities of the tropospheric microwave trans-horizon propagation above ocean surface and the marine atmospheric environment characteristics has important significance for the short-term prediction of the trans-horizon propagation and for the designs and the applications of the radio-communication systems. In this paper, based on the transmission loss data collected in the oversea experiment at 14.1 GHz on the area of Yellow Sea and Bohai Sea of China and the synchronous meteorological data collected from the meteorology grads tower which founded in the transmitter station, the relativities of the transmission loss and the evaporation duct height are analyzed with wind direction, wind speed and the difference of air temperature and sea temperature, respectively. The usability of the coastal meteorological data for the tropospheric microwave trans-horizon propagation is studied, and the results are validated with the parabolic equation method and the Advance Refractive Effects Prediction System (AREPS). The conclusions are helpful for the study of the propagation characteristic and the short-term prediction of the tropospheric microwave trans-horizon propagation above ocean surface.
