摘要：

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.
