The relevance of the work is due to the intensive development of space communications facilities, which leads to an increase in the target tasks assigned to rocket and space technology products, and, accordingly, an increase in the number of radio-electronic equipment and antenna-feeder systems. The number of radio-electronic devices in rocket and space technology products can reach several dozen units, while the area for their placement is limited. As a result, a situation arises in which the distance between the antennas can reach several meters. The proximity between different systems leads to interference between transmitters and receivers using a limited frequency resource when operating together in a single space and time.

A methodology has been developed to evaluate the electromagnetic compatibility of radio-electronic means of rocket and space technology products, taking into account the spatial attenuation between antenna systems, as well as taking into account out-of-band radiation from transmitters and side channels of receivers.

The analysis of out-of-band radiation from transmitters and side channels of receivers of the product, affecting the electromagnetic compatibility of the spacecraft, is carried out. The spatial attenuation between the antenna systems of a rocket and space technology product has been calculated. Electrodynamic models of antenna systems of rocket and space technology products have been developed. Their electrodynamic characteristics at various frequencies are determined.
