Rain Attenuation Analysis using Synthetic Storm Technique in Malaysia

open access: yesIOP Conference Series: Materials Science and Engineering, 2013
Generated rain attenuation time series plays an important role for investigating the rain fade characteristics in the lack of real fade measurements. A suitable conversion technique can be applied to measured rain rate time series to produce rain attenuation data and be utilized to understand the rain fade characteristics.

Slant Path Ka-Band rain attenuation statistics in equatorial Malaysia obtained using stratiform convective-synthetic storm technique [PDF]

open access: yesInternational Journal of Engineering & Technology, 2018
In the design of satellite communication link, rain attenuation statistics is essential information for system designer to realistically determine link availability and provide means to combat system degradation. Due to the limitation of available measured data in equatorial regions especially for high frequencies (Ka-band and above), the prediction ...

Prediction of Time Diversity Gain – Comparison Between ITU-R P.618-13 Using a Concept of Rain Rate with Delay and Synthetic Storm Technique

open access: yesInternational Journal of Interactive Mobile Technologies (iJIM), 2022
Future satellite companies will use higher Ka and V bands. Rain fade is the most important issue in establishing reliable communication between Earth and satellites outside the 10 GHz band. The problem is exacerbated in the tropics by significant rainfall throughout the year. One way to deal with rainfall attenuation is to use a time-diversity strategy.

Transfer Functions and Linear Distortions in Ultra-Wideband Channels Faded by Rain in GeoSurf Satellite Constellations

open access: yesFuture Internet, 2023
Because of rain attenuation, the equivalent baseband transfer function of large bandwidth radio-links will not be ideal. We report the results concerning radio links to/from satellites orbiting in GeoSurf satellite constellations located at Spino d’Adda,

Performance analysis of the synthetic storm technique rain attenuation prediction model on Nigerian climate

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract This study analyzes the performance of the synthetic storm technique (SST) over the Nigerian climate. The location of interest was 9.91°N, 8.88°. Two months rain rate time-series data measured by a rain gauge located inside the University of Jos, Nigeria was utilized for the purpose of this work.

Investigation of the ground displacement in Saint Petersburg, Russia, using multiple-track differential synthetic aperture radar interferometry

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2020
Global sea level rise and local land subsidence might exacerbate the risk of flooding in coastal plains. Among other cities, this is also the case for the high-latitude city of St. Petersburg, which has long been threatened by flood events.

Improvements in Storm Surge Surrogate Modeling for Synthetic Storm Parameterization, Node Condition Classification and Implementation to Small Size Databases

open access: yes, 2021
Surrogate models are becoming increasingly popular for storm surge predictions. Using existing databases of storm simulations, developed typically during regional flood studies, these models provide fast-to-compute, data-driven approximations quantifying
