Actually, some specially designed SAR can see through buildings, but not the kind of SAR that’s in publicly available remote sensing data.
One example (of many): https://www.kurzweilai.net/seeing-through-walls-in-real-time https://www.kurzweilai.net/seeing-through-walls-in-real-time
- CamperBob2 6y agoExactly. "SAR" is a very broad term encompassing various ways to make an antenna seem larger than it is. That's about all you can say about it, generically speaking. 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. .... it's probably time to hire some marketing folks.

- mncharity 6y ago> it's probably time to hire some marketing folks Engineering PhD students coached on outreach presentation of their thesis sometimes improve dramatically in just a few hours. Some not so much.

- yborg 6y agoThat has a range of 20 m and produces an image of an amorphous blob out of a stationary target. They also don't give the frequency or the power used. Doing this with a 100 kg satellite from 525 km away would be slightly more difficult.
