Or just calculate directly. I think the angular
resolution of an array or a telescope in radians is
something like

0.22 * wavelength / aperture .


Oops. That's 1.22 .

Still, I don't think it's too bad considering how
long ago I learned about synthetic aperture
arrays in 2nd year physics.

Hasn't this problem been solved already? We scan the cosmos with large
radio antenna arrays to form images of celestial features.
