The paper deals with the designing of equipment for telecontrol of changes in the temperature of the internal layers of objects, which cannot be measured by contact methods. The bases for this are an analysis of the ultrasound oscillations reflected from the internal heterogeneities of the environment, as well as restoration of the pattern of a pressure propagation velocity along the sounding beam. The feasibility of telecontrol of temperature is analyzed by using the boundary integrated equations. A procedure is proposed on the basis of the difference-phase method for estimating the velocity of propagation of reflected signals. Requirements for the equipment and algorithms for processing the signals observed are formulated. Ways for further studies are directed.
