Abstract :
In this paper a hybrid model has been developed based on a physics-based model for the forest and a ray-tracing algorithm. Using the physical model of the forest, effective dielectric constant is found and applied to the raytracing algorithm. This 3-D modeler can consider objects with different shape and position, and therefore the simulator can be used for any arbitrary scenario.
