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.
Clever, but I bet the chaff is easier to create by other means. Chaff
is sized according to frequency of the receiving units. I have no idea
what that would be for modern sets, but in WWII, "window" was fairly
long (12-18") aluminum coated card stock that was chucked out of
bombers or "pathfinders" to screw with the primitive German radar.
Five hundred bombers looked like five thousand over five times the
area = crappy radar guidance for anti-aircraft.
Funnily enough, I just read of field trials getting underway for an
"electric bullet" which is essentially a plastic, non-lethal
projectile in standard police-issue calibres that delivers a strong,
piezo-electric charge that stuns people in a similar fashion as a
taser, but over a far greater range and with similar accuracy as a
regular bullet. Your "RF pulse shell" is not dissimilar.
