Morphological control of artificial ionospheric hole and its short-wave propagation effects
人工电离层洞形态调制及其对短波传播的影响

As one of important and effective means for modifying the ionosphere, chemical release can produce artificial ionospheric holes attributed to ionization depletion, which also greatly affect the short-wave propagation. In this paper, a neural gas multi-point release dynamics model is proposed baseed on mono-point one, and then the morphological control effects of chemical substances, releasing altitude, releasing mode and mass on artificial ionospheric hole are discussed. Furthermore, the short-wave propagation effect of artificial ionospheric hole is simulated and investigated by the 3-D numerical ray tracing.
