The integration of various types of electronic devices on board aircraft, which is a stable trend in their development, potentially allows to improve almost all indicators of their perfection: efficiency, survivability, informativeness, while realizing higher efficiency in solving an increasingly expanding range of tasks. However, in practice, this inevitably leads to an increase in the negative impact of electronic means on each other, due to the impact of unintended radio interference due to both basic and various kinds of non-basic radiation and interference, often negating the potential gain due to the integration of electronic means.

In this regard, the problem of ensuring electromagnetic compatibility becomes extremely urgent, the neglect of which can negate all the predicted potential advantages of an on-board radioelectronic complex.

The purpose of the article is to consider the peculiarities of the occurrence of various types of unintended radio interference and their distribution channels both inside and outside the fuselage of the carrier aircraft.

The article considers the classification of unintended radio interference by sources and places of their occurrence, by objects of influence, by interaction space. Unintended radio interference caused by radio transmitting and receiving devices is considered in more detail.

The systematization of unintended radio interference is aimed at identifying ways to reduce their impact on the performance of electronic means in the process of their joint operation as part of an on-board electronic complex.

Further in a series of subsequent articles, the following will be considered:

methods for evaluating and ensuring electromagnetic compatibility of on-board radioelectronic devices and radioelectronic complexes;

the main indicators of electromagnetic compatibility of avionics and complexes and methods of their assessment;

the influence of electromagnetic compatibility on the system performance indicators of on-board electronic equipment (efficiency, survivability, dynamism, etc.);

the main domestic and foreign regulatory documents in the field of electromagnetic compatibility;

promising areas for improving methods for ensuring electromagnetic compatibility of on-board electronic devices.
