Kevin and all,

The radio observation method used for meteors is called "forward scatter
".  It is somewhat difficult to explain so I will give you a link for an
overview of the method.

In essence, I am using ionization reflections off of far distant tv
video carrier waves that are created when a meteor collides with Earth's
atmosphere. It is sort of a poor man's radar but it works with high
definition.  If I can answer any questions off-list regarding the method
I will be happy to.  I also made an innovation by merging my radio array
with an experimental all-sky video camera that has been supplied to me
by Sandia National Laboratories. So I am capturing visual fireballs with
their unique scatter reflections.

I do all this work with "nature recording" in mind.

On a feathery nature note: I am looking for an ID for a certain owl that
landed atop the dome of my camera last full moon. There is a .mp4 movie
at the below link. If you are into birds then you might like this little
video clip.
