What is ULA forward-backward averaging?

Hello All,

Could you please explain what is that in easy words? When it should or should not be used?

If the ULA antennas are laid over the East - West axis, with antenna 1 most to the West and antenna 4/5 most to the East, is North forward and South backward, or do I misunderstand?

Thank you very much.

Unless you have some very specific purpose for ULA, using ULA is not recommended.

Backward-forward averaging is just a technique that aims to reduce the effect of multipath with ULA arrays. There’s no rule as to when it should be used, you’ll need to test and see if in your application it improves results, or makes it worse. Results are entirely up to the environment.

Ok, that is enough for me, thank you again.
