Rain Attenuation in Broadband Satellite
2007 Asia-Pacific Conference on Communications, 2007This paper presented the effects of attenuation from rain rate together with rain drop size distribution analysis on the model of transmitter broadband satellite in Ka-band frequency. We illustrated a new model by simulating transmission broadband signal and studied the rain attenuation which has effects to high frequency. The results of the model were

A rain attenuation model for the SIRIO‐SHF experiment
Atmosphere-Ocean, 1982Abstract Rain attenuation statistics at 11.6 GHz and 32° elevation angle deduced from one complete year of measurements near Milan are compared with the statistics obtained from a model storm and surface measurements of the rainfall rate. Two different assumed vertical profiles of rain are able to reproduce the attenuation statistics but each of the ...

Cumulative Distribution of Rain Rate and Rain Attenuation in Ukraine
2019 3rd International Conference on Advanced Information and Communications Technologies (AICT), 2019The estimates of communication outages along slant Earth-Space links and near-surface links in the worst periods of the year were made for the first time on the territory of Ukraine with usage a consideration of microclimatic point of view. These calculations were based on the cycle of continuous rain rate observations as well as of experimental ...

Rain Attenuation and Radio Path Design
Bell System Technical Journal, 1970This paper describes the application of the rain attenuation theory of Ryde and Ryde to the design of Radio Systems. It shows that an upper bound on the outage time due to rain attenuation can be computed from a measured point rain rate distribution. The paper also describes a suitable rain gauge.

Rain attenuation measurements in Malaysia
2015 1st URSI Atlantic Radio Science Conference (URSI AT-RASC), 2015Within a research programme dealing with the development of a 5.8 GHz link to be used as redundancy for a 26 GHz terrestrial point-to-point microwave link in the equatorial region, two problems are discussed in this paper. a) Drop size distribution (DSD) and the associated specific rain attenuation and b) Frequency scaling of rain attenuation ...

Radar Reflectivity and Attenuation of Rain
Journal of Applied Meteorology, 1963Abstract The radar reflectivity and attenuation of rain are computed for various empirical drop-size distributions using more accurate and systematic calculations of the back-scatter and attenuation cross sections from Mie theory. Reflectivity-rainfall (Z-R) relations for 3.2 to 10 cm, incorporating deviations from the Rayleigh theory, are found to be ...

Abstract : The statistical properties of rain attenuation which dominate propogation at frequencies above 10 GHz are required for planning radio systems at these frequencies. These properties are studied for three frequencies, 11.2, 12.7 and 18.76 GHz and various link lengths, 2.5, 5, 7.5, 10, 12.5 and 15 mi at six locations in Canada.

Rain Attenuation at Millimeter Wavelengths
International Journal of Infrared and Millimeter Waves, 2002A method of determining the rationality for raindrop size distribution is first presented. The relative volume occupied by raindrops is derived. The attenuation and cross-polar discrimination induced by rainfall at millimeter waves are investigated with the incoming expression and a brief analysis is presented.

Rain will be estimated with the formation of cloud consists of water droplets, at higher frequencies such as millimetre band, that experiences a signal degradation and signal reduction due to the cloud consists of water droplets. The atmospheric gases, clouds, rain, snow, fog, cloud droplets, noise, water vapour, hydrometers absorbs electromagnetic ...
