Now take a look at this map image, and go back and forth to see if you feel that the X i marked is a reasonable approximation of the photographer's location
Now take a look again at the SAR image and tell me if you can see any artifacts from the front of the building through the roof (hint, zoom in and look for the curved line of bright dots :) )
But now that I have a better understanding of the layover effect I think it might just be that the satellite is looking from where it looks like the sun is shining, and it's directly imaging that front window frame and brick wall. Need our SAR pro to comment :)
The brick wall at the front, though, has the exact same curvature as the dots, dead-on.
