What is the "Y-factor method" in RCS-Measurements??

[rcsge]

I read in an article that they were using the "Y-factor method" to measure and compute the noise figure of the system.

What does Y-factor method mean??

Dear scge,
The Y-factor is defined as the ratio of System temperatures :- P(hot) to P(cold). For full details go to the following website:
