You're mixing things up there. Signal Strength is NOT an indication of bearing... it's an indication of how strong the signal is compared to background. Kind of a Radio version of Sonar's SNR values. You can have an extremely low SS and still get very accurate bearings. What SS will NOT give you is a range estimate. As I hinted at, there have been a few collisions at sea that were caused, in part, by operators assuming that lower SS equated to more distant contacts, that that is not always a true statement.
Now, needing multiple receptors for bearing accuracy is a true thing - that's basic beamforming, and those principles work the same way for radio and sound waves. So, going back to some of my earlier comments on this, depending on the ESM suite and equipment installed, bearings can be taken from the system with some degree of accuracy.
