摘要
利用微波测距机,在南澳岛海域的跨海路径上两点之间进行连续测距,由所测两点距离的起伏变化,反算出测量路径海面上大气折射率的起伏变化。结合岸边梯度仪测得的陆上大气参数,提出了建立陆海交界海域海面上大气折射率起伏预报模式的初步构架,并根据现有的实测数据进行了海上大气折射率结构常数的计算,为研究海上湍流大气对电波传播的影响提供了更为合理的环境参数测量依据和方法。
By using a tellurometer, the distance of a propagation path between Nan＇ao island and the mainland coast is continuously measured. The fluctuation of the atmospheric refractive index over the sea could be deduced from that of the distance. Combined with data from the on-land gradienter, the principle structure of the forecasting model to the refractive index fluctuation is proposed near the oceanterrestrial interface. Based on the observational data, the structure constants of the refractive index are calculated, which could provide more reasonable criterion and technique to environmental parameter measurements in researching bow the turbulent atmosphere affects the radio wave propagations.
