Though only with human intervention.

Aren't there ham radio buffs who try bouncing radio waves off meteor trails?

Actually, Ham operators don't "bounce" waves off meteor trails. When a meteor vaporizes in the atmposphere, it produces a burst of radio noise. This noise can be easily detected with a standard receiver.

I did this last year during the Leonids and was surprised how easy it was. I used a 2 meter receiver with a magnetic mount car antenna. I was hearing about 10 bursts per minute at a frequency of about 144 Mhz (can't remember the frequency exactly...my records are at home). I even recorded the bursts on a standard cassette tape and played them for my students the next day. They all gave me a look that said, "Oh my God! He is recording STATIC!"

The reading I did indicated that you can even detect the burst in the FM radio band if you find a quiet station. I tried this, but living between Chicago and Milwaukee, fat chance of finding a station quiet enough.

Yes, they do.

(And they do your stuff, too.)

Actually, a meteor doesn't produce radio noise that amateurs are interested in.
It creates an ionised trail which is perfect for bouncing radio waves off. Such trails are usable for a few minutes.

Amateurs use distant radio stations as beacons for this. If they hear it for a minute or two before it fades, it's bouncing from a meteor trail.
