Paper Abstract

We describe two new methods for phasing arrays of heterodyne receivers. Both can be used when the arrays are sparse and distributed. One is based on the iterative transform algorithm using a support constraint and the other on maximizing image sharpness. Both work well; they require a modest number of speckle realizations with the same aberrations and are relatively immune to measurement noise.
