【摘要】 为了获取蒸发波导特征参数，考虑到舰船无线电系统的实际环境和架设条件，建立了一种基于地面气象测量的蒸发波导预测系统。首先，在船尾后边的船舷上架设非接触式红外温度传感器测量海表温度。然后，在船尾平台上架设高6 m的高精度气象传感器，获取温度、气压、湿度和风速风向等气象参数。最后，利用蒸发波导预测的P-J模型和海气通量模型预测出蒸发波导高度。实验结果表明：该系统能够达到较高精度预测蒸发波导特征参数的目的，且具有性价比高、布设方便的特点。更多还原

【Abstract】 In order to obtain the evaporation waveguide characteristic parameters, a prediction system for evaporative waveguide based on ground surface meteorological measurement is established, considering the actual environment and installation conditions of ship radio system.Firstly, non-contact infrared temperature sensor is set up on the ship rail behind the stern to measure sea surface temperature.Then, 6 m height high precision meteorological sensors is set up on the stern platform, meteorological parameters, such as temperature, air pressure, humidity, wind speed and direction, are obtained.The P-J model predicted by evaporation duct is used and the evaporation duct height is predicted by air-sea flux model.The experimental results show that the system can predict the characteristic parameters of evaporation waveguide with high precision, and has the characteristics of high cost performance and convenient layout.更多还原
