Thank you Carlos,
Now I know I did not give a stupid option to the yard.
I assume that the advanced radars used for warfare do have that doppler
option
to filter out the reflection from a moving object.

Anyway, I am just curious, how does a normal marine radar separates wave
clutter
from echos from ships. Just by suppressing weaker signals?
