Yarman Geometric Norm or Impedence Normalization

I'm working with some old software to optimize antenna networks, and I've come across some stuff that I don't understand. For the software to run, all impedence values entered must be normalized to 1 ohm. What does it mean to normalize an impedence and how do I do it? Also, the manual for the software keeps referring to a Yarman geometric norm when it talks about normalizing these impedences. What is a Yarman geometric norm?
I apologize if I sound daft. Any help would be much appreciated!

I'd guess that normalization would just be dividing all impedances by the characteristic impedance of the system you are working with (50 Ohms or 75 Ohms, etc.). But I suppose it could be more complicated than that. The manual doesn't list any references? Does the company still exist and have a website? If not, do you see any author names that you could try to figure out how to contact to ask your questions?

Oh, okay! That actually makes more sense considering that the software uses the real frequency technique.
