AESA is just the way you form and steer the beam and listen for the return. It doesn't automagically mean your beam is less detectable or harder to jam. It's the tricks that are easier to deploy with AESA that achieve that - noise-like signal, higher receiver sensitivity allowing for lower emission power, clever signal processing etc.
