摘　　要：针对短波天波信号快衰落的瑞利分布规律,分析了信号快衰落对通信干扰效果的影响,结合有效干扰的准则,研究推导了在短波快衰落情况下,形成有效干扰所需要的干扰信号和通信信号场强中值之比,为短波通信对抗装备的设计提供技术参考。Based on the Rayleigh distribution of fast fading of sky wave transmission in short wave comunication, the fast fading transmission＇ s influence on jamming effectiveness is analyzed. The effective jamming criteria, the ratio of jamming signal to field strength median of communication signal for effective jamming in the presence of fast fading transmission is deduced. These findings may be useful in design of short wave communication electronic warfare equipments.

关 键 词：快衰落 瑞利分布 干扰效果 场强中值 干信比
