Abstract: The results of the solutions of actual problem  - the precision (at a level not less then 3,3·10-6°Ñ) temperature control of a sapphire high-overtone bulk-acoustic resonator are presented in the paper. Necessity of thermal stabilization of system construction based on two thermoelectric modules connected in series with introduction of a damping layer between them is justified. A control system has been synthesized taking into account the dynamic properties of such a structure, an algorithm of its configuration is described, features of transients are investigated. The results of simulation of thermal stabilization system, proving the fundamental possibility of creation of a generator on a sapphire high-overtone bulk-acoustic resonator for modern radar systems with high sensitivity and resolution, are presented.
