I'm looking for a scientific approach that will minimise the trial and error
So far i'm thinking...
Antenna-based DF Ideas:
* Omni-antenna dopplar array
* Loop antenna (i suspect this won't work effectively as a DF antenna at
such high frequencies, but i need to explore this further ;)
* Directional antenna w/ search-pattern software controlled stepper motors
(all directions) rotating head and signal meter or spectrum analyzer
Secondary, bolt-to-directional-antenna DF Ideas:
* GPS and AHRS (or if not an AHRS then digital compass and digital
* Powerful laser technology?
Or some combination from all the above.
BTW, I have or am building equipment to try all the above with the exception
of the laser stuff. My research is for a different application than is the
situation proposed here, but there are many similarities in the problem
