Phase-aberration correction using signals from point reflectors and diffuse scatterers: basic principles
S.W. Flax,Matthew O'Donnell +1 more
TL;DR: The method presented here has no need for a beacon or an ideal point reflector to act as a source for estimating phase errors, and uses signals from random collections of scatterers to determine phase aberrations accurately.

Phase-aberration correction using signals from point reflectors and diffuse scatterers: measurements
Matthew O'Donnell,S.W. Flax +1 more
TL;DR: A method based on cross-correlation measures between neighboring elements in a phased array, using signals reflected from diffuse scatterers, significantly reduced the effects of these aberrations, producing images nearly identical to those generated in the absence of aberration.
