description FIELD: physics. ^ SUBSTANCE: invention is intended for ultrasonic nondestructive control. Ultrasonic antenna array contains prism and piezoelectric cells installed thereon at preset angle of its acoustic axes to working surface of array. Prism is arranged in the form of periodical stepped structure, every piezoelectric cell is installed on separate step of prism, distances along acoustic axes of piezoelectric cells from them to working surface of array being equal. ^ EFFECT: increase in equipment resolution at the account of improvement of ratio signal/noise. ^ 2 dwg
