摘要：
The method for reconstructing object images in cross-sections using a circular antenna array when sounding space by an ultrasonic monochromatic wave is proposed. The image reconstruction is carried out by scanning the internal structure of the object placed inside the circle controlled by the focus of the circular antenna array. An algorithm for controlling the phase shift modules in the elementary radiator channels of the circular antenna array for changing the focus position is presented. Model results of the reconstruction of the image of the simplest point objects are presented. The problems of implementation of a circular array are discussed.
