It's more similar to an antenna that isn't an array. But you could compare an antenna array to a microphone array, sure. They both work by tweaking the phase and relative gain to arbitrarily change directivity without a need for physical directivity techniques. Like how home voice assistants and multi-antenna wifi APs achieve long distance reception without also amplifying 360 degrees of noise. They do a thing not unlike camera autofocus in that they quickly home in on whatever optimizes s/n.
