Stochastic 3D Foliage Modeling at 80 GHz: Experimental Validation and Ray Tracing Simulations

A stochastic modeling methodology for 3D foliage is presented, aimed at enhancing ray-tracing simulations. The model supports adjustable stochastic geometry, density, and shape to capture variability in foliage structures. The model is validated through experimental measurements of representative vegetation. The influence of foliage density and size on path loss and RMS delay spread is analyzed to demonstrate the applicability of the model in the 80 GHz frequency band.
