Comparison of the synthetic storm technique with a conventional rain attenuation prediction model

IEEE Transactions on Antennas and Propagation, 1986
It is confirmed that the synthetic storm method is in some way related to one year's existing attenuation data in Greece, but that also one of the standard models (in particular Lin's empirical) works as well and even better. Since agreement between prediction and observation has not been clear for the synthetic storm technique, an extension of the ...

Annual and Diurnal Slant Path Rain Attenuation Statistics in Athens Obtained With the Synthetic Storm Technique

IEEE Transactions on Antennas and Propagation, 2006
We present annual/seasonal rainfall rate statistics derived from a 29-month data bank of 1 sample/min, measured by a disdrometer located inside the National Technical University of Athens Campus. We discuss both the inaccuracy and the unavailability of the measuring equipment, as well as the statistical reliability of the rainfall rate sample ...

Time series prediction of rain attenuation from rain rate measurement using synthetic storm technique for a tropical location

AEU - International Journal of Electronics and Communications, 2014
Abstract A comparison of measured attenuation series with the attenuation series obtained from rain rate measurement by using synthetic storm technique is made for Ku band signal at a tropical location. Validity of the model is tested for the long-term statistics in terms of the cumulative distribution of attenuation occurrence and fade duration ...

Analysis of Synthetic Storm Technique Based on Ku-Band Satellite Beacon Measurements in Malaysia [PDF]

open access: yes, 2014
Most of the existing rain attenuation prediction models were proposed based on measurements taken in temperate climates. These models are found not accurate in tropical regions and were thus modified in order for such models to be applied in tropical regions.

Impact of Link Elevation Angles on Rain Attenuation Statistics in Heavy Rain Region Predicted Using the Synthetic Storm Technique [PDF]

open access: yes, 2017
In the absence of measured rain attenuation, prediction models are the best way to estimate statistics of rain attenuation. Synthetic Storm Technique (SST) model is one of the solutions to obtain time series of rain attenuation. By using SST, we will investigate the impact of link elevation angle on the prediction models; in particular, the results ...

Application of synthetic storm technique to predict time series of rain attenuation from rain rate measurement for a tropical location

2012 5th International Conference on Computers and Devices for Communication (CODEC), 2012
A comparison of measured attenuation series with the attenuation series obtained from rain rate measurement by using synthetic storm technique is made for Ku band signal at a tropical location. Validity of the model is tested for the long-term statistics — the cumulative distribution of attenuation occurrence and fade duration.

Global formulation of the Synthetic Storm Technique to calculate rain attenuation only from rain rate probability distributions

open access: yes2008 IEEE Antennas and Propagation Society International Symposium, 2008
Equation (2) is likely a global mathematical model of the parameter m(thetas, f ), to be used in the probability formulation (1) of the synthetic storm technique. Equation (1) is a robust and easy to apply formula because it does not require rain rate time series to estimate rain attenuation probability distribution in satellite links, but only rain ...

Prediction of Rain Attenuation Statistics from Measured Rain Rate Statistics using Synthetic Storm Technique for Micro and Millimeter wave Communication Systems

2018 IEEE MTT-S International Microwave and RF Conference (IMaRC), 2018
This paper presents the suitability of the Synthetic Storm Technique (SST) for converting the rain rate statistics into rain attenuation statistics for different tropical and temperate locations. Prediction of rain attenuation statistics at different frequency and elevation angle is directly made from the measured rain rate statistics and compared with

Slant Path Attenuation and Microscale Site Diversity Gain Measured and Predicted in Guam with the Synthetic Storm Technique at 20.7 GHz

open access: yes, 2013
We report the first test of the Synthetic Storm Technique (SST) at the equator, in the Isle of Guam, where NASA has installed an interferometer at its Remote Ground Terminal Complex, composed of two terminals separated by 600 m in the North–South direction.
