Abstract. The problem of finding the antenna aperture field distribution by measurements in the area of near radiated field is searched. Two approaches: the reduction  and the focusing methods are considered. The features of these methods as well as accuracy aspect are analyzed. It is shown that the focusing method has several advantages and can provide accuracy acceptable for practical applications.

Key words: aperture distribution, the method of measurement in the near field, the method of recovery, focusing antenna, measurement precision.
