That might not even be necessary because the satellites are transient phenomenon with predictable trajectories. This makes it more a matter of data cleaning to remove them.
Imagine someone walking through a log exposure photography shot. You can filter out the frames or pixels with some extra work.
- itishappy 2y agoNit: Lucky imaging requires multiple frames, not long exposures. In short, you need multiple frames to be able to reject any. Long exposure times are still important for astronomy because they improve the noise floor.
- s1artibartfast 2y agolong exposure was intended to describe the photography analogy. Im not an expert in digital radio astronomy, but my understanding is that data is generally sampled at a high rate.
- itishappy 2y agoShoot, you're totally right. I hadn't considered this is radio.
