SEAMCAT Specific Implementation

SEAMCAT propagation model P.452-16 implements clutter loss following the method of application as described in Recommendation ITU-R P.452-16:

1. the basic propagation loss is first computed for the portion of the path between the positions of Tx and Rx clutter, considering nominal clutter heights as antenna heights;
2. the additional loss due to protection from local clutter is then added to the previously computed basic propagation loss. There is a predefined set of clutter (ground-cover) categories that the user can choose from: Suburban, Dense suburban, Urban, Dense urban, High-rise urban, and Industrial zone. The user can also specify other clutter conditions by introducing the corresponding Tx/Rx clutter nominal heights as well as the distances from Tx/Rx antennas.

The additional clutter loss is not suitable if the clutter distance d_k from the respective terminal is not significantly greater than the distance between the terminals d. In SEAMCAT, the clutter loss is computed only if:
