Abstract

The interference immunity of radio communication systems has always been considered an actual topic. Especially when it comes to information in military. In the modern theory of military confrontation, more and more importance is attached to the introduction of new control systems based on network-centric principles, while the basis of such a control system is the communication subsystem. In this connection, on the one hand, communication systems must meet the stringent requirements of the system of command and control of troops and weapons, on the other hand, in the conditions of modern confrontation, they themselves are subjected to destructive influence from the enemy. The basis for modern destructive impact on radio communication systems (RCS) are the use of electronic warfare (EW) and electronic suppression (ES). The methodology for assessing the impact of the ES on the RCS is now sufficiently developed, which updates the research directions in the field of interference protection of the RCS. This article is aimed at the prepared reader and is addressed to teachers who teach at military universities and classifies about the research carried out to improve noise immunity of the RCS in the dynamics of the EW. A comparative analysis of methods for increasing the noise immunity of the RCS is presented. It is reasonable to consider the method of pseudo-random adjustment of the operating frequency of the hopper as one of the fundamental in solving problems of increasing noise immunity. The main types of interference affecting the RCS and their classification are considered. The notion of electronic warfare as a basis for modeling the processes of interaction between the RCS and the EW (S) means is introduced. The main methodological approaches to the modeling of electronic conflict, the features of using a different mathematical apparatus for such modeling are considered. The indicators of stealth and noise immunity of the RCS in the application of the pseudo-random tuning of the operating frequency regime in the dynamics of the electronic conflict are presented.

Summary

Introduction

The purpose of passive radio masking is to reduce the signal energy available to the reconnaissance vehicle in order to reduce its visibility. It is necessary to reduce the levels of spurious and unintentional emissions of radio electronic systems and means of reconnaissance objects. The first two methods, refer to the provision of systems that are protected from intelligence, but go beyond the actual conflict between two RE Another thing is special ways to reduce the levels of unintended, incidental and secondary (reflected) emissions. Suppression of the source of interference is carried out by the optimal design of electrical circuits and the layout of printed circuit boards, taking into account the requirements for minimizing spurious generation, created internal elements of devices and circuitry These measures include the following objectives: isolation of power supply circuits, elimination of radiating conductors, reconstruction or elimination of especially noisy (generating) circuits. The latest achievement is due to the use of special non-reflective forms of reconnaissance objects, and through the use of measures to increase the energy absorbed by the targets (through the use of special coatings and other methods and means)
