This simple example illustrates modeling terrain effects. The TerrainProperty models an obstacle that blocks the communication from the Sender to the Receiver if the communication path between them intersects with the terrain shape. When you run this model, the sender will emit a signal twice per second. The Receiver will move around the Sender and measure the received power. It then plots the received power on a polar plot. The plot shows that the receiver can only receive the signal (with power value larger than 0) when it is not shadowed by the terrain model.
This model uses the LinkVisualizer to display a line between communicating nodes.
