海上蒸发波导中电波传播特性实验研究

摘要

As sea warfield becomes more and more important,we pay great attention of radio wave propagation characteristics in oceanic evaporation duct in the experimental investigation. We put forward the experimental methods of radio wave propagation charac- teristics in the evaporation duct. These methods study changes in the atmospheric refractive index, including radiosonde detectors, weath- er analysis,prediction system and deductive method. The simulation and contrastive analysis are performed for these three methods ac- cording to specific experiment data. The results show that the deductive method is closer to the theoretical predicted values.%随着海战场日趋重要，对电磁波在海面蒸发波导中传播特性的研究越来越被重视，研究方法更是成为备受关注的问题。提出了蒸发波导中电波传播特性的实验方法，主要对大气折射率的变化进行了研究，方法包括无线电高空探测仪、气象分析与预测系统和推导预测3种。通过具体的实验数据对几种方法进行了仿真与对比分析，分析表明推导预测的方法更接近理论预测值。
