Abstract: The required level of noise immunity of radio electronics is provided among other things, by ensuring electromagnetic compatibility of radio electronic equipment. However, its estimation becomes a rather time-consuming task when the number of radiating elements increase. The article presents methods for estimating electromagnetic compatibility of radio electronic equipment with multi-element antenna systems when exposed to mutual interference based on solving low-dimension equations. Methods for constructing a comparison system based on Lyapunov vector functions, as well as on a low-dimension Kalman filter, are presented. The results of mathematical modeling of the developed methods with the original 4x4 MIMO system are shown. The signal/noise ratio and interference power are considered as evaluation criteria. The results of the study show the possibility of using these methods when evaluating the electromagnetic compatibility of radio electronic equipment with multi-element antenna systems.
