I never wrote that SN is an indication of strength. However, the way bearing is analyzed in at least a large portion of naval ESM systems is by calculating the different strengths on the different antenna nodes, and interpolating the bearing. There might be other methods for bearing analysis, but the process I described is definitely in use.

Definitely true. I'm not sure what I wrote that gave you the impression.

In the Cold War era? Enough for TMA?
