Focused? A big dish belching lots of microwave will fry everything
between you and the target, as well as everything beyond the target,
that's inline (and in accordance with inverse square law). Unless
your focused EMP or HERF gun is not a precision weapon unless you
happen to be flying it overhead. Hmmm... that reminds me of
something.
In a previous life, I played RF engineer and had some experience with
direction finders:

In about 1990, I played with a direction finder system that used two
or more RC (radio controlled) helicopters, balloons, or airplanes.
Each flying machine contained a receiver, GPS, and telemetry
transmitter. When a signal is heard, the telemetry transmitters send
the relative phase of the received signal and the various GPS
satellites. No need to send the lat-long-altitude of the flying
machine as this can be calculated from the various satellite delays.
The position of the transmitter can be calculated from the relative
delays. The system worked well enough in a simulator, but fell apart
in the field for various stupid reasons. The main problem was that
this was about 1989, when GPS was called Navstar, had only 8 out of 24
birds, GPS receivers cost $2000/ea, and the whole mess was too heavy
to fly, even with a balloon. Another great idea before it's time.
Anyway, one application of such a direction finder is to locate an
unwanted user on a wireless LAN, fly a helicopter or airplane
overhead, and drop something smelly and disgusting from above. While
not as effective as a HARM missile, it's far more precise and cheaper.
