For long range use, you'll probably need a radio xmitter, as you suggest.
The DF (direction finding) techniques for radios are pretty much all in the
receiver end of it.  Not my specialty.

However, once you get near the "crash" site, I would suggest a loud pieso
beeper.  We've searched for hours in weeds and tall grasses for small
rockets that were within a few feet of us.  A beeper would have reduced
that time to seconds.
