This article contains information about the active protection systems (APS) of commercial information from leaking into the environment through random antennas (RA). The different models (verbal, physical, mathematical, simulation) will complement each other and constitute a single composite model during engineering of APS. Analysis of the effectiveness of various types of noise (noise barrier, simulating sighting, additive, multiplicative, etc.) in the APS has been performed using the method of statistical computer simulation modeling (SSM). Analysis of the comparative effectiveness of different types of noise used in APS has been performed. It has been shown that simulating interference are significantly more effective than noise interference in the APS of RA. The verbal and pictorial models considered in the paper allow us to turn to the mathematical and physical modeling of possible implementations of APS of RA. The construction of the device for creating a low-energy simulating noise type for APS of RA has been suggested. The transmitter modulus model for operation in the APS based on the four-element dual-polarization antenna with disk emitters has been developed. The results of experimental research of the device layout have been presented in the article. The isolation between antenna\'s transmitters is greater than 17 dB in the frequency range 2–4 GHz, that is why amplifiers with a gain of up to 15–16 dB can be integrated in the transmitter modulus scheme without loss of its stability. The transmitter modulus implements a non-linear multiplication of the commercial information signal and the signal of parametric pumping. This multiplication is equivalent to a combination of amplitude and angle modulation, which forms simulating interference significantly more efficient in comparison with conventional noise.
