  • As influenced by geomagnetic field, electron density fluctuations of ionospheric irregularities are highly elongated in the direction of geomagnetic field, and the scattering of the irregularities are also highly directional, which could be potentially used as long-distance communication circuits in VHF band. Based on the characteristic of ionospheric Field-Aligned Irregularities Scattering (FAIS), an anisotropic scattering model of ionospheric field-aligned irregularities is proposed in the geomagnetic reference frame. The parameters such as path loss, delay spread and coherence bandwidth of forward and back scattering are calculated by the model. The results of Radar Cross Section (RCS) predicted by the model have a good agreement with data in literatures. The model given herein can be helpful to construct ionospheric irregularities scattering communication systems in VHF band.
