Propagation Path and Related Tropospheric, Phenomena on the Satellite-Earth

Abstract

Attenuation is a major drawback for the field of satellite communication which we can not ignore, but, ofcourse can try to mitigate at an instant. In this project, my focus is on the attenutaion part. I am trying to explain the types of attenuation which is being faced by the signal at tropospheric region. We will see how the signal changes its properties when it passes through tropospheric region. Different type of models is being used by the research scientist for measurement of the attenuation impact over the signal. Many times the models has given the fruitful result but some time they are failed as per different location. I took the Ku-band signal from NSS-6 (geostationary 950E) at an elevation angle of from Kolkata. My result outcome shows that the ITU-R model is the best model out of them and it makes the best predictions for different tropical climates. Based on my experimental result, I am trying to show that the ITU-R model is the best option for our climate. On the other side, I have explained through my project that how much signal depolarized at the different percentage of time at one-minute rain rate distribution.
