摘      要：The characteristics of high-frequency(HF)electromagnetic(EM)wave propagation can be affected when EM waves propagate in the *** ionospheric irregularities appear in the ionosphere,they can have a serious impact on the propagation of HF EM *** this study,the propagation of HF EM waves in ionospheric irregularities was investigated by numerical ***,a twodimensional model of plasma bubbles was used to produce ionospheric irregularities in the ionosphere.A ray-tracing method was then utilized to simulate the propagation of HF radio waves in these ionospheric *** showed that the propagation of HF radio waves in the ionosphere was more complex in ionospheric irregularities than without ionospheric *** addition,corresponding ionograms were synthesized by radio rays propagated in the ionosphere with these *** synthesized ionograms were then compared with the experimental ionograms recorded by an *** showed that spread F could be simulated on the ionograms when ionospheric irregularities occurred in the *** result was consistent with the ionosonde observations.
