| Abstract: |
| Objective to research the characteristics of microwave attenuation in sand and dust storms. Methods According to the electromagnetic wave propagation theory in discrete random media, expressions for attenuation and phase shift coefficients for a medium with sand and dust particles are derived. Results Computations show the predicted values from the proposed attenuation formula are an excellent agreement with the values by Goldhirsh’s formula, which verified the validity of proposed formula. Expressions for total attenuation and phase shift in earth satellite links for sand and dust particles are also derived. Predictions made with proposed formula are compared with results obtained by Sharief’s formula and Erdenekhuu’s formula. The attenuation values calculated by the proposed model are good agreement to those obtained by Sharif’s model. Conclusion The results verified the accuracy and validity of the proposed formulas, which are simple and suitable for different frequency, a quick and easy way of calculating attenuation. |
