BTW, does anyone know of a good web resource on radars? (Most of the
stuff I can find from Google is a bit basis).

If you don't mind some math, I'd look at EW 1010 on the Journal of
Electronic Defense website. You'll have to register, but it's easily worth
it. It will give you a fairly good tchnical overview or radars, EW systems,
electro-optics, etc.

This looks useful, thanks.

In their discussion of LPI radar, they talk about Random Signal Radars,
which really do use a random (not even pseudo-random) signal. It works
because the emitter keeps a copy of the signal it sent and can compare it to
the time-late return and extract a useful signal. The RWR can't do that
nearly as easily because it doesn't know what was sent.

Indeed it doesn't. But, OTOH, it does have a *much* more powerful
signal to work with.
