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 :)
Interestingly it does seem to see right through the awning that's to the right of the roof.
There appears to be a couple tables that are hiden from Google's satellite view but clearly visible to the bottom right of the building in the ka band SAR image.
That's odd, but you can see in the SAR photo that there isn't even an outline of the awning, nor the golf carts under it, nor the columns that hold the awning up, but there are trees which aren't there in the photos from the ground.
While I can't find the image online earlier than 2010, there's an ieee research paper titled TanDEM-X for High-Resolution SAR Interferometry from 2007, so it certainly could predate the awning.
