Unless the pulse is tied in timing to the one that is sent out by the
receiving sets, there will be no distance information. It wouldn't
help people find you at all.

Radio and GPS have obsoleted this kind of thing. "Hi, I'm here within
this 30 foot diameter circle. Come save me." Even my cell phone has
GPS in it now.

I have never used radar so this idea may be useless (ok, so almost
all
of em are) but.....
Producing an intense burst of RF is fairly easy by firing a magnet
through a properly shaped coil. This is done in new EMP weapons
where
the power output is high enough to fry nearby electronics. So, why
not
use the same idea in a 12 guage shell dsigned to fit in one of those
flare launchers. The charge fires the magnet through the coil (this
is
destructive as the coil disintegrates) producing a short intense
pulse
of RF that will appear on the radar scope. Maybe it could also fire
a
cloud of chaff into the air to make a longer lasting return. The
idea
is that the initial pulse will get the operators attention and then
the
chaff would allow him to see the source.
