| Abstract A computer model is presented for the performance assessment of HF ionospheric communication links. The proposed model considers the effects of the natural and artificial ionospheric disturbances on the radio waves propagation parameters and modes. The ionosphere and radio wave parameters are first derived for specified ionospheric communication links. The natural and/or artificial disturbances are assumed over the link path, and the resulting modified propagation medium and wave parameters are then estimated and compared with their corresponding parameters for quiet ionosphere. Hence, the link performance is evaluated and guide lines for retuning the communication link are proposed to control (enhance or disrupt) the ionospheric communication links. The ionosphere and wave parameters are derived for different communication links subjected to natural disturbances due to different solar activities, solar flares, and geomagnetic storms. Several communication links are also analyzed under the effect of artificial modification by HF ionospheric heaters. | ||||
