【摘要】：蒸发波导预测模型的适应性研究对电磁波的传播、雷达通信及战术指导有着十分重要的意义。根据蒸发波导的探测原理,为了研究蒸发波导NPS模型对南海海域的适应性,在我国南海海域搭建了一套气象梯度仪测试设备,获取了大量的海洋水文气象数据,并仿真分析了空气温度、相对湿度、气海温差、风对蒸发波导高度的影响,将蒸发波导高度实测数据和NPS模型预测值进行了对比分析与验证。实验结果表面,稳定条件下NPS模型预测的蒸发波导高度的偏差值随气海温差呈现出近似线性变化规律。该文的研究成果对南海海域蒸发波导预测模型的选择具有一定的指导意义。
[Abstract]:The study on the adaptability of the prediction model of evaporative waveguide is of great significance to the propagation of electromagnetic wave, radar communication and tactical guidance. In order to study the adaptability of the evaporation waveguide NPS model to the South China Sea, a set of meteorological gradiometer test equipment was built in the South China Sea, and a large number of marine hydrometeorological data were obtained. The effects of air temperature, relative humidity, air sea temperature difference and wind on the height of evaporative waveguide are simulated and analyzed. The measured data of evaporative waveguide height are compared with the predicted values of NPS model. The experimental results are compared and verified. Under the stable condition, the deviation value of the evaporative waveguide height predicted by the NPS model shows an approximate linear variation with the air-sea temperature difference. The research results in this paper have some guidance for the selection of the evaporative waveguide prediction model in the South China Sea. Meaning.
