摘　　要：短波电子信息装备以电离层为信号传播媒介辐射,能实现地面距离数千公里的通信、探测和电磁信号侦收。而电离层复杂的时空变化特征,会对短波电子信息装备性能能否充分发挥产生极大的影响,因此,在各型短波电子信息装备建设过程中,必须充分考虑不同作战时间下的短波电离层信道变化。文中开展了短波电波传播衰落特性与时间场景特征关联研究,为短波电子信息装备论证设计、研制和试验训练等提供支撑。Shortwave electronic information equipment radiates signal through the ionosphere and can complete communication, detection and electromagnetic signal detection at a distance of thousands of kilometers on the ground. The complex temporal and spatial variation characteristics of the ionosphere will have a great influence on the performance of the shortwave electronic information equipment. Therefore, in the construction of various shortwave electronic information equipment, the variation of the shortwave ionosphere channel under different operational time must be fully considered. In this paper, the correlation research of shortwave propagation fading characteristics and time scene characteristics is carried out, which provides support for shortwave electronic information equipment demonstration design, development and experimental training.
