Microwave (MW) and millimeter-wave (mmW) propagation are severely affected by dust storms and sand storms in arid and semi-arid areas. Electromagnetic waves may suffer from attenuation due to suspended particles during a dust storm. This paper proposes an empirical model to predict the attenuation due to dust storms based on a one-year measurement of visibility, humidity and their effects on MW links...
A field study on dust storm effect on Microwave links in arid area covering a wide range of radio frequency was conducted for seven months in Khartoum, Sudan. The study involves computerized monitoring of Transmitted and Received signal levels of (TRSL) of six Microwave links operating at Ku (14GHz) and Ka (21GHz) bands as well as an automatic weather station. This paper presents a description of...
A study on dust storm effect on Microwave links in arid area covering a wide range of radiofrequency was running for one year in Khartoum, Sudan. The study involves computerized monitoring of Transmitted and Received signal levels of two Microwave links operating at (14GHz) and (21GHz) as well as an automatic weather station. This paper presents a description of the experiment and reports results...
Dust storms are significant meteorological phenomena which attenuates signal level especially at Ku band and higher frequencies with direct impact on telecommunications system performance. Few prediction models have been developed to calculate the attenuation due to dust storm in dB/km. All prediction models have assumed that the intensity of dust storm is uniformly distributed around the area covered...
In this paper an adjustment factor which reflects the vertical variation of dust storm (earth satellite links) has been derived based on the analysis of the vertical dust storm behavior. The paper has been divided to four parts. First an introduction to the dust storm phenomena and its effect on microwave signal attenuation. Secondly, observations of the behavior of the vertical dust storm intensity...
