A new model is presented to predict rain rate serially during a rain event at a tropical location. The model is based on the Gaussian distribution of the conditional occurrence of rain rate with a particular value of the rain rate occurring before. The mean and standard deviation of the distribution are modeled with the measured data. The rain rate at a particular time instant is predicted from the knowledge of previous samples. The predictor has tested well with a mean error within 10% for rain rates above 20 mm/hr for 10 sec time interval. The same technique is also successfully applied to predict time series of rain attenuation. The practical application of channel predictor is also shown in this paper for FMT simulation. ©2009 IEEE.

Development of channel model to predict rain rate and attenuation for FMT applications

Applied Electromagnetics Conference, AEMC 2009 and URSI Commission B Meeting

Propagation measurements at Ku-band over an earth-space path have been carried out at Kolkata (22°34'N, 88°29'E) by receiving a signal at 11.172 GHz from the satellite NSS-6 (geostationary at 95°E) since June 2004. The amplitudes of the co-polar signal and the cross-polar component have been monitored along with rain rate and drop size distribution measurements by an optical raingauge and a Joss-type disdrometer, respectively. The relationship between rain attenuation over the earth-space path and the rain rate gives an assessment of raining conditions along the satellite path. Fast fluctuations of the satellite signal amplitude are studied to indicate the effect of small scale irregularities associated with the rain events. TRMM satellite data obtained with PR and TMI indicate that the rain rate has a distinct control of rain height which increases with the former, the relationship depending on the type of rain. The propagation measurements and TRMM data have been used to study the features of rain at Kolkata. © 2007 American Institute of Physics.
