Statement of the problem. to increase the energy efficiency of radio-electronic systems based on the use of laser radiation in the presence of interference.

Purpose. development of a model of the process of adaptive control of the laser power in the interests of ensuring a given level (in terms of power) of the signal reflected from the irradiated object at the input of the optical radiation receiver.

Results. a model of the process of adaptive control of the laser radiation power was proposed. The adaptation principle is implemented on the basis of the use of the mathematical apparatus of the theory of automatic control, which made it possible to represent the cyclical nature of the studied laser ranging process in the form of closed feedback transitions. The adequacy of the proposed model is substantiated using the MATLAB software environment and its Simulink dynamic systems simulation package.

Practical significance. the developed model and the principle of adaptation of the laser radiation power level implemented in it can be applied in the design of optical systems for various purposes (laser ranging, laser communication, laser target designation, etc.), the efficiency of which is affected by space-time and interference conditions.
