摘　　要：本文着重研究不同因素对电磁波在海表反射方面的影响,并建立HF无线电波传播模型,提出利用控制变量法和灵敏度分析的思想来分析不同海洋条件对高频无线电传播的影响。同时,结合蒙特卡罗法及微元法,从概率统计角度提供一种传播仿真算法。为验证模型的正确性,将这一过程离散化并采用蒙特卡罗方法和微元法进行了模拟。This paper focuses on the influence of different factors on the reflection of the electromagnetic wave on the sea surface,and establishes the HF radio wave propagation model. The influence of different ocean conditions on high frequency radio transmission is analyzed by using the thought of control variable and sensitivity analysis.At the same time,combining Monte Carlo method and infinitesimal element method,a communication simulation algorithm is provided from the perspective of probability and statistics.In order to verify the correctness of the model,the process is discretized and simulated by Monte Carlo method and infinitesimal element method.
