A technique for correcting the amplitude-phase distribution of the aperture field in the antenna array has been investigated. The optimal number of points for placing the reference oscillator was determined. The specified number provides for achieving the efficiency of superresolution algorithms. A correction technique based on presenting the antenna array in the form of large-radius array consisting of ideal noninteracting elements was proposed. This technique involves the use of only one reference point. Using the MUSIC method, as an example, the direction finding characteristics were calculated for the techniques under consideration.
