The results of modeling elements of active protection system (APS) of computer equipment from the leakage of confidential information (CI) into the environment through random antenna (RA) are presented. The baseline for computer modeling capabilities in the form of ultra-wideband RA are considered. Equivalent circuit of the interaction of ultra-wideband RA and relay module (RM), which is a generator simulation interference (SI) in the APS of CI. The elements of the equivalent circuit RA and RM are part of the APS of CI commercial purpose. The mathematical model of the interaction of RA and RM corresponding to a given equivalent circuit is proposed in the paper. Intermodulation conversion process ultra-wideband (noise, noise-like) signals on non-linear element which is part of the RM, is presented. It has been shown that simulation interference are formed in RM circuit by the stochastic amplitude and angle modulation of the received signal. The experimental spectrogram of the noise signal at the output of the MR confirms the proposed theoretical model.
