How does imaging radar work?
Imaging radar works by bouncing a radar signal off the ground, then measuring the strength of the signal that comes back and how long it takes. From this information, we can answer questions like:
- Is the terrain high or low?
- Is it wet or dry?
- Is it rough or smooth?
- Are the surfaces straight up and down (like walls) or slanted (like hills)?
- Is the surface covered with grass or concrete?
