The article investigates the issue of improving the level of environmental in communication systems and data transmission of radio monitoring complexes. The relevance of this task is due to the complexity of the modern electronic environment, which is characterized by high dynamics and saturation with electronic means that work on radiation and have a mutual impact, as well as the importance of tasks performed by military radio monitoring units. The paper proposes the use of the algorithm of multichannel weight spatial processing of signals against the background of interference to improve the obstruction of communication systems and data transmission on the basis of the radio relay station "R-415V". This approach is the most rational, since the compensation of existing obstacles is carried out subject to the presence of spatial differences between the directions of the arrival of a useful signal and the obstacle that it is typical for radio relay stations. In addition, the technical prerequisite for the implementation of the proposed solution is the presence in the radio relay station "P 415V" of the directional antenna "DB11", consisting of two identical z-emitters and is the simplest two-element antenna grille that can be used to implement multichannel weight treatment. The article presents the spatial processing algorithm, selected performance indicators and investigated the effectiveness of its work. The calculations were carried out using the computer algebra system – Mathcad 15. Were obtained visual, quantitative and qualitative results of performance indicators depending on the selected electronic situation for certain tactical and technical characteristics of the means of transmitting information without taking into account the influence of destabilizing factors on the quality of processing.
