摘要：

The article describes the simulation of thermal processes of a multichannel radar. For this purpose we propose a new phenomenological model based on governing dynamics in form of a system of ordinary differential equations. Solution to the system describes real-time thermodynamics of non-equilibrium system (PCUs in RECs). The resulting temperature series of the radar at the most heat-stressed operating modes are shown. On the basis of the developed model of thermal processes, a block-diagram of an algorithm has been synthesized, which makes it possible to predict the values of temperature and block overheating failure in real-time and with high precision.
