I've never heard of "SAR", that's very interesting... But I am curious, if the data truly comes from only radar, why are shadows apparent in many of the created images? Or does the same surface reflect radio waves differently based on whether it is in the sun or not?
- Carropola 8y agoRadar sends pulse. Radar moves. Radar looks at reflections from previous pulse. Because radar moved before waves returned and is now looking at the area from a different angle making the image appear illuminated from elsewhere. Its not the suns shadow but a radar shadow. Like if you took a picture with a flash and managed to reposition your camera to a different angle before the light from your flash reached the target.
