Definition of Scatterer in Electromagnetic Wave Propagation Environment Using Image Processing Based on FDTD Method

In this paper، we implement real irregular terrain model in computer program by using image processing. We show how this approach can be used in simulation of E. M. wave propagation on irregular earth’s surface in a realistic manner. Some simulations are performed for implementation of longitudinal height differences over the propagation path as PEC surface. We also describe that how this approach can be used for any boundary condition in computational space. The results observed in Snapshots of the field profiles taken at different simulation times، validates capability of this method.
