This article considers the process of constructing software and hardware models of complex radio systems. The principles and problems of mathematical modeling in the general scientific sense are given. Particular attention is paid to simulation methods with computer algebra. The general requirements for the development of a simulation model of a complex radio environment are given. The main components of systems of hardware-software models of complex radio engineering conditionsare considered. The article also details the concept of "digital twins." The possibility of integrating software and hardware models of complex radio engineering into a virtual training ground for testing aerospace defense systems,is demonstrated. Permissibility of use of the modeling, adapted to the tasks of electronic warfare.
