Adaptive Noise Generator for Masking Side Electromagnetic Radiation and Interference

Abstract

The article analyzes the possibility of constructing a noise signal source of adaptive multichannel noise generators to provide active protection of informative components of side electromagnetic radiation and interference (SERaI). Had reviewed technical solutions of the noise generators to mask SERaI. Domestic and foreign literature, patent documentation confirming the relevance of the creation of adaptive noise generators for masking SERaI were analyzed. It was identified that in current noise generators designed to mask SERaI, there are shortcomings. It is shown that the improvement of the characteristics and expansion of the fields of application of such devices is possible due to the creation of multichannel adaptive noise generators. In such noise generators in each noise masking channel it is proposed to provide both the power adjustment of the emitted signal and frequency band modification. In order to achieve this objective, quasi-harmonic noise signals are used as a carrier and control oscillations for the purpose of forming the initial noise signal in each noise channel by modulation methods.
