摘　　要：蒸发波导是海洋上出现频率最高的波导,能引起电磁波的异常折射,研究蒸发波导的特性对于分析海上电磁波的传播规律具有很重要的意义。研究了气象要素对蒸发波导特征量的影响以及对电磁波传播的折射效应,分析了在渤海地区的测试过程中对蒸发波导环境实时监测的可行性。Evaporation wave-guide is the wave-guide that appears most frequently on the sea, may lead to abnormal refraction of electromagnetic wave, studying the characteristics of evaporation wave-guide is important to analyze the propagation rule of electromagnetic wave on the sea. This paper studies the influence of meteorological elements on evaporation wave-guide characteristics and the refraction effect on the electromagnetic wave propagation, analyzes the feasibility of real- time monitoring evaporation wave-guide environment in the course of testing Bohai sea area.
