Rain Attenuation at Terahertz
Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a specific rain attenuation model for prediction methods recommended by ITU-R. Measurements of Terahertz wave taken at 313 GHz (0.96 mm) were compared with our calculations. Result...
متن کاملMeasurement of Rain Attenuation in Terahertz Wave Range
Rain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four raindrop-size distributions, e Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull distributions, and using a specific rain attenuation model for prediction methods rec...
متن کاملRain Attenuation Prediction for Terrestrial Microwave Link in Bangladesh
Rain attenuation is a major shortcoming of microwave transmission. As a subtropical country, Bangladesh is one of the highest rainy areas of the world. Thus, designing a terrestrial microwave link is a serious challenge to the engineers. In this paper, the annual rain rate and monthly variation of rate are predicted for different percentage of time of the year from the measured rainfall data. U...
متن کاملMicrowave Attenuation in Rain; a Dual Wavelength Radar Study
Microwave attenuation in rain at C-band. observed in radar data from Alberta. Canada, has been assessed by means of two different estimators: one employing KDP measured simultaneously by an S-band radar and the other a comparison of synchronised Sand C-band reflectivity measurements. While good agreement between the two has been found in some cases, in others the second method gave a larger est...
متن کاملMicrowave Attenuation Studies Due to Rain for Communication Links Operating in Malaysia
Attenuation due to rain is an important constraint in the designing of the microwave communications links operating in Malaysia especially at frequencies above 10 GHz. In recent studies, the ITU-R proposed models for the prediction of rain attenuation give a good estimation for the microwave propagation loss caused by rain for the temperate regions but it underestimates the rain attenuation pre...
