This paper describes a technique that allows a severely distorted coherent optical array receiver to produce images comparable to conventional monolithic imaging systems. The technique is based on using a phase synchronizing point source as a reference to eliminate phase errors in the array. Once phase corrected, the individual elements in the array can be coherently combined to yield a resolution equal to the overall size of the array, and if Doppler information is available, separation of targets within the diffraction limited spot size of the array is possible. Experimental verification of concepts developed within this paper is presented for array receivers operating at 633 and 514 nm.
