DigitalTwin of the Seminatural Modeling Stand Based on a Matrix Simulator

The article considers the digital twin of the stand for seminatural simulation of the radio-electronic environment. The stand is built on the basis of a matrix simulator, a two-channel transmitter, receiving antennas and a two-channel receiver. The digital twin is based on a mathematical model composed of mathematical models of individual parts of the stand. The mathematical models of parts of the seminatural modeling stand are described. The description of the developed software, in fact, a digital twin built on the basis of this model, is given. The digital twin is used to accompany the ongoing experiments on the stand for seminatural simulation and to interpret the results. The result of the digital twin is a file with samples of the complex envelope of the signal that simulates the real received signal. The main advantage of using digital twins is their ease of use from the end user’s point of view.
