Actually, some specially designed SAR can see through buildings, but not the kind of SAR that’s in publicly available remote sensing data.

Impulse radar with range gating substitutes time resolution for spatial resolution, and has been used to 'look' through walls with varying degrees of success. I think you can even buy a studfinder that uses similar principles.
Also, when you catch yourself writing things like this:
One of our radar scientists accurately
described the phenomenon (to reporters,
presumably): It helps to think of it
just as your brain’s interpretation of
a two dimensional representation of the
coherent sum of backscatter responses
from electromagnetic waves.
Engineering PhD students coached on outreach presentation of their thesis sometimes improve dramatically in just a few hours. Some not so much.
