I agree with you on all points.

See below, but passive radar obviously can be done since
there are reports of its use with meteor counting and such.
I don't see any real benefit of passive radar over active
radar except that you don't have to worry about FCC regulation
with passive radar. The signal processing for passive radar
seems more complex.

The only problem I have is with your classifying this friend's
radar with "passive radar". Since it is emitting a radio signal,
it is active radar. Still, I think active radar is a great
addition to any field station if you can afford it. Its great
that he lists how to build it and everything!

A very good report. Just the sort of report I like to see which
describes the field setup up in detail and presents results
(although I would like to know if any more results were
generated using the system since the report was published in

Also, the report is good in pointing out that even though the
radar "saw" something, nothing was visible with the eyes.

Also, of interest is the requirement of most active radars to
rotate. The described setup antenna was fixed.

Of course.
