This paper describes a wavefront compensator applicable to microwave imaging antennas that are so large as to be inevitably distorted. Measurements are made of the radiation field due to a single point source located in the general direction in which imaging is performed. Feed-back-controlled circuitry focuses the array upon, the source notwithstanding the unknown a priori distortions within the array. The paper concentrates upon tolerances and system limitations. An experimental example of a two-dimensional radar map with nearly dif-fraction limited resolution is given. The 3 cm wavelength array was 40 m in length and the element position errors exceeded 1 wavelength in all dimensions.
