一种基于人工扰动电离层的通信对抗技术研究

研究了扰动后的电离层对不同波段的电磁波传播的影响,并探讨了该项技术在通信对抗上的具体应用。结果表明:受扰电离层可以引导VLF波进行"哨声模式"传播,进而实现对潜通信;可以使得HF波传播轨迹发生偏转、逃逸、聚焦和散焦,进而实现短波干扰;可以降低卫星通信频率,进而利用新波段实现卫星保密通信,同时还能产生透镜效应,对实现卫星通信的VHF电波产生额外增益,增强通信效果。

A new communication countermeasures technology based on artificial disturbed ionosphere

onospheric disturbances produced by artificially chemical releases have many applications in radio wave propagation. In terms of 3-D ray tracing method, the ray trajectories of HF waves through the perturbed ionosphere are investigated. The ray trajectory changes include focusing, defocusing, multipath fading, or leakage of the signal out of the ionosphere. In addition, the disturbed areas may act as guides for VLF waves propagate in whistler mode through the ionosphere, and at VHF, the signals propagating from satellites to the ground, the ionospheric hole produces slight focusing. Also, the practical applications in communication coun- termeasures by artificial disturbed ionosphere are discussed.
