Özet
In this study, the procedure of new model development steps has been presented starting with plane earth measurements. A propagation model experimentally derived from both free space and near ground plane earth path loss models for pine tree forest with foliage depth lower than 400 m has been proposed. It is a piecewise model taking foliage depth of 150 m as a boundary. Different from Weissberger, ITU-R and COST235 models, the proposed one takes trunk height gain k into account. Mean error has been obtained as 6.55 dB for proposed model, 31.72dB for CO5T235, 17.42 dB for Weissberger and 21.03 dB for ITU-R at 900 MHz.
