Wind influence on radio waves propagating through vegetation at 1.8 GHz

The impact of moving vegetation on propagating radio waves under the influence of wind had been investigated. It was found that the fast-fading component of the vegetation-shadowed signal, originating from a line-of-sight (LOS) transmitter, resembles a Rician distribution. From the measured data, a...

Zusammenfassung:The impact of moving vegetation on propagating radio waves under the influence of wind had been investigated. It was found that the fast-fading component of the vegetation-shadowed signal, originating from a line-of-sight (LOS) transmitter, resembles a Rician distribution. From the measured data, a new empirical model at 1.8 GHz of the Rician k-factor has been proposed. The model characterizes the dynamic impact of the wind influence for radio waves propagating through vegetation. The proposed model was then assessed against a different set of measured data and was found to be in close agreement.
