The efficient design of reliable communication link requires the knowledge of rain fade margin to be provided in the system design to overcome the losses in the signal strength due to rain over the path. Hence there is need for the development of reliable and accurate propagation model for attenuation prediction at the operating frequency of the link at particular location. Therefore study of rain-induced effects on microwave propagation was undertaken at Guru Nanak Dev University, Amritsar. This paper describes the measurement of zenith path attenuation due to rain at Amritsar (31° 38′ N 74° 52′ E) India, using zenith looking radiometer operating at 20 GHz. The effective rain height has been obtained from the analysis of the radiometric data and point rainfall intensity. Specific attenuation for various rain rates in the present study has been evaluated from measured drop size data using lognormal drop size distribution. The average effective rain height at Amritsar has been estimated and compared to that of predicted by ITU-R model. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR] |
