I assume that due to the rotation of the earth that when Arecibo emits a radar beam that other radio-telescopes on earth collect? Otherwise only objects within Arecibo’s relatively narrow FoV (that are also very close to earth) would be detected - so wouldn’t a purpose-built (and steerable!) radar emitter be more useful?
- notthemessiah 6y agoArecibo was steerable, that's what the receiver array was for.
- Aeolun 6y agoSort of, 5 degrees isn’t exactly a lot.
- mulmen 6y agoNope, it transmitted and received. The range was limited to about Jupiter because the dish would move over the effective horizon before the signals returned. Pretty incredible!
