Features of mathematical modelling of complex of radio engineering systems (RES)

The article deals with the construction of mathematical and computer-dimensional models of complex radio systems, allowing to estimate the quality of their functioning, at the design stage, before carrying out natural tests. The features of modern radio systems, complicating the task of their research and design by simulation. These features include: hardware and software complexity of the RTS, the stochastic nature of the proceeding in the RTS, the processes, the combination of a high rate of change of radio signals with a relatively low rate of information flow. Provides specific ways to facilitate the process of constructing mathematical models of complex radio systems, radio signals and radar interference. A general sequence of steps for creating mathematical model of the radio system and conducting research with the help of the PC.
