I'm far from being an expert here, but aircraft RWR can give an accurate bearing. I'm sure ECM systems on submarines is even more sophisticated.

ESM would be enough to get a bearing if nothing else I assume? Perhaps with two sensors on the same mast, you could use the geometry to get a range estimate but it would not be hugely accurate.

I think that the most important aspect of ECM signal apart from bearing is the signal strength. Sure, it won't tell you the exact range but it can help.
