Hello DJM,
thanks for your reply.
No, I can't see a shadow - I see a clear visible bearthline - and this is the problem.
A radar is working like following method: An electronic radio wave is send by the radar beam; it hits a wall, a ship or what else inside the visible line and is reflected by such object. The radar beam receives the echo and calculates the distance by the time the signal needs from sending to receiving.
Like already noted, ONLY OBJECTS IN A CLEAR VISIBLE LINE. In conclusion to this: Nothing behind a object exept higher buildings than the first in line.
So normally you wouldn't see the bearth behind the building because the buliding is to high for the radarmast.
