AAKEE : I do not want to add to this UAV rumour, but the picture you posted is from a synthetic display where anything can be filtered out, specific SSR codes and even Primary returns.
What would be interesting to see is what the Swedish Military primary radar displays show. On the other hand a small ,slow moving and mostly composite UAV would not offer much returns.
