ITU-R Path Loss Model of Semi-ARID Region

---

Abstract

Rainfall fade slope is an important factor that system engineers consider when developing fading mitigation procedures (FMT) for microwave systems in space-earth situations measures the rate at which rain attenuates radio signals. The accuracy with which the ITU-R's suggested fade slope prediction model approximates the distribution of fade slopes within tropical regions has been confirmed by a recent analysis conducted in Kurnool, India. The entire year-long measurement effort yielded results that are in good agreement with empirical data. Furthermore, the findings were validated by a meticulous cross-referencing of the information collected for this study with rainfall records in hierarchical data format (HDF view) obtained from NASA's HDF view.
