Abstract
In search of an accurate location-centric rain-induced attenuation model, in this paper, the authors have investigated the measured attenuation and rainfall intensities at a few locations in India, namely Amritsar, Kolkata, Kondapalli, and New Delhi. The proposed model predicts rain-induced attenuation as a function of a few location-centric parameters, like the height from the mean sea level, the latitude, elevation to the satellite, the rainfall intensity, and the frequency of the signal which the measurement is made at. The proposed model shows a very good agreement with measurements over a few locations in Malaysia, Singapore, Nigeria, Cameroon, Fiji, Thailand, Papua New Guinea, South Korea, Kenya, Indonesia, and the Netherlands. The validation of the model-based attenuation also shows a very good match with the Tropical Rainfall Measuring Satellite (TRMM) -retrieved path integrated attenuation (PIA) over the locations in India used in this study. The model-based attenuation values show a good match with the rain-induced attenuation obtained from the ITU-R model using the TRMM-retrieved rainfall over these locations.
