摘　　要：敌方在对进行天波传播的短波跳频电台实施引导跟踪干扰时,将不再满足干扰椭圆的关系,而需要重新通过干扰方程进行研究。通过详细分析,首次给出了在天波传播模式时,现有跟踪水平下,对不同跳速的短波跳频系统实施有效的跟踪干扰的条件,最后给出了降低跟踪干扰效能的几种有效策略,为提高短波跳频系统全面的抗跟踪干扰能力指出了发展思路。When the foe implements the directed tracking jamming on the short-wave frequency hopping（FH） radio station with sky-wave propagation,the relationship of jamming ellipse won＇t be met with,and the new relation will be studied by jamming equation. This paper presents the conditions to implement the effective tracking jamming on the short-wave HP system with different hopping speed in sky-wave propagation mode under present tracking level for the first time,finally gives several effective strategies to reduce the efficiency of tracking jamming,points out the development thought to enhance the all-sided anti-tracking-jamming capability of short-wave HP system.
