The performance of a synthetic aperture array consisting of N identical multiline transmitter apertures is presented using the far-field integrated irradiance as a performance index. Results are presented of the variation of these indices with subaperture separation, number of subapertures, random piston errors and those resulting from pointing of the synthetic aperture for single and multiline transmitters. A brief discussion of the pathlength control requirements generated by this performance analysis will then be given along with a novel multiline focal plane phase retrieval algorithm.
