If I were to make accurate polar measurements, I don't see a need for anything more complicated than a large lazy susan bearing and two sheets of plywood with degree markings every 5 degrees. They do make automated turntables and I suppose it wouldn't be terribly hard to make some PIC based motorized turntable rotator, but why?

My lazy susan/MDF was easy but its the 5 degree markings that I SUCKED AT
Well, if you wanted to get elaborate, You could get one of these:

and use the hand controller.

Quite informative, actually.
You have a constant directivity beamwidth of +/- 15° there.
Tractrix, is it?
