Incidentally, radar is used for asteroid and comment tracking, although
the initial observation is normally optical.  This is one of the primary
activities of Arecibo, and it has a 1MW feed point, 10s of Terrawatt
EIRP, transmitter for this purpose.  Although not within the definition
of SETI (it is called SETV or SETA) I would think that optical detection
would be the most reliable method of detecting non-human engineered
spacecraft in the earth's vicinity.

Planetary radar transmissions are around 2.4GHz and wouldn't result in
echoes in the frequency range used by S@H.  They would result in echoes
in the frequency range used by project Phoenix, but they wouldn't book
time that conflicted with radar transmissions, and don't provide
data for public processing.

So I guess all I can do is scan the dark nights with my telescope. It would
be really great if the radar data was open for public analyizing.

Otherwise, I would agree that the question reflected a rather poor
understanding of what the client does.

Dude, I just downloaded the thing about 2 weeks ago and I am a busy man, I
read up on it as much as possible. It was not a poor understanding, it was a
lack of understanding. Which can be corrected, in time.
