The idea of ground clutter sounds cool, and using real SRTM data sounds interesting, if complex. Be careful though, since this data was taken by the space shuttle, areas that are far north or south are not available because it's impossible for the orbit of the space shuttle to cover all of the earth. Before you start, I would make sure that you have enough data for Estonia/Scandanavia, as I think the northern limit is around there somewhere.
