摘　　要：目前短波天波通信场强估算的研究仍然集中在对传输损耗的估算,而实际天波场强的估算还包括电波传播距离计算、天线方位水平方位角和水平方位增益等多个方面的内容。基于此,本研究以无线电传播理论为基础,结合已有的短波天波传播损耗计算模型、球面几何与天线理论,建立了一套短波天波通信场强估算的方法与模型。该模型能够对短波通信效能、短波通信干扰能力以及短波通信干扰效能进行评估,具有较强的应用价值。Field strength estimation of HF sky-wave involves the calculation of radio wave propagation dis- tance, horizontal azimuth, horizontal azimuth gain and others, while currently most studies are merely fo- cused on the estimation of transmission loss. In light of this, based on radio propagation theory, and in combination with the existing propagation-loss calculation model of HF sky-wave, spherics and antenna theory, a set of method and model for field strength estimation of HF sky-wave is established. This model could effectively evaluate HF communication effectiveness, HF communication interference ability and jam- ming capability, and this is of fairly great application value.
