| description | Potential capabilities of a system of separate protection against combined interference with the introduction of additional reception channels detuned in frequency are considered and a comparison of its potential capabilities with the capabilities of a traditional system of separate protection against combined interference is given. Additional receiving channels are offset in frequency relative to the main ones by an amount exceeding the width of the probe signal spectrum. At the output of these channels, passive interference is absent (as well as useful signals from the target), which makes it possible to compensate for the level of active interference for the entire power of the protection device against active interference. The work has been brought to a schematic solution. The difference between the proposed scheme is reduced only to the fact that the weight vector of spatial processing in it is formed by the output oscillations of additional spatial reception channels, which are tuned in frequency relative to the main ones by the same value exceeding the width of the spectrum of the probing signal of the external information sensor. Modeling of circuits (models) of the comparative noise protection systems was carried out in the MATLAB environment. The power ratio signal / (interference + noise) at the outputs of the comparative circuits was used as an indicator of efficiency. The frequency offset between the main and additional reception channels by a certain amount was also investigated. Thus, under the conditions Intensive combined interference, the effectiveness of the system of separate protection against combined interference with the introduction of frequency-tuned additional reception channels can be close to the effectiveness of the optimal joint processing of signals against the background of interference. The gain grows as the inter-period correlation coefficient of passive interference grows. Further development the studies carried out are seen in the practical verification of the developed model for analyzing the effect of combined interference on the receiving devices of the external information sensor of aircraft, as well as for substantiating the corresponding requirements for the creation of protection systems against combined radio interference.
