Abstract

The chemical release experiment by a single point-source can trigger simple ionospheric perturbations, which have an effect on signals of limited frequency and are difficult to influence signals above VHF. Based on complex releases using the combination of Ba and SF₆, a new release approach is presented. The amplitude scintillations and the phase scintillations of VHF, UHF, L bands which are represented by 150 MHz, 400 MHz and 1 000 MHz signals respectively are calculated with the theory of horizontal stratification when they propagate through the disturbed area. The results show that multi-scales ionospheric disturbance effects induced by this method can influence radio-wave signals above VHF dramatically and the effects decrease with the increasing frequency.
- ionosphere,
- chemical release,
- radio propagation effect,

- ultra high frequency
