摘　　要：电离层E层对短波的吸收作用强,F2层对短波反射作用强、吸收弱.电波经电离层反射一跳到达接收机,其电离层吸收损耗包含E层反射吸收、F2层反射途经E层的吸收.引入了E层的短波吸收损耗模型,通过实例介绍了短波传输路径相关参数及其计算,并最终完成短波E层损耗计算.计算结果有助于了解短波损耗的来源、提高短波通信技术、改善短波传播质量.The E layer of the ionosphere has strong absorption to shortwave,while the F2 layer has strong reflection and weak absorption of shortwave.The shortwave is reflected by the ionosphere to reach the receiver,and the ionosphere absorption includes the E layer reflection absorption and the E layer absorption through it the F2 layer reflection waves.Model of the shortwave absorption from the E layer was introduced,and the relevant parameters and their calculations of the shortwave transmission circuit were presented through the example.Finally the shortwave E layer loss calculation was completed.The calculation results are helpful for understanding the source of shortwave loss,promoting shortwave propagation technology,and improving the quality of shortwave communication.
