Abstract
A method of objects image reconstruction in sections by means of a ring antenna array with space sounding by an ultrasonic monochromatic wave is proposed. The image reconstruction is carried out by scanning the internal structure of the object placed inside the ring controlled by the focus of the ring antenna array. A control algorithm for phase shifters in channels of elementary radiators of the ring antenna array for changing the focus position is described. Model results of image reconstruction of elementary point objects are presented. The problems of ring antenna array implementation are discussed.
