“…In most cases, synchronization can be carried out using satellite systems, however, when working in a difficult jamming environment and to increase the autonomy of a multi-position system, it is advisable to develop a synchronization system for the system itself. A variant of the synchronization system proposed by the authors is given in [5].…”

Modern wide development of science and technology causes the growth of information needs in all branches of human development. At present, there are all opportunities to increase information security by combining sources of information into a single system. At the same time, when merging, specific difficulties and features emerge, which together make it difficult to implement the proposed solutions. The paper considers the peculiarity of combining different types of radar stations into a single information system. Errors of measurements of separate parameters and their influence on system characteristics are considered. Options for solving the problems that have arisen are proposed.

The work compares and evaluates options for the distribution of forces and means of organizing the security of the base camp during hostilities, therefore, a methodology for the rational distribution of forces and means of security of the base camp by the mobile reserve of the defense force brigade during hostilities has been developed.The probability of holding the base camp was chosen as an indicator for evaluating options for the distribution of forces and resources. The value of the indicator depends on the success of the security organization of the base camp during hostilities. The probability of success of the security organization of the base camp during hostilities will be determined by the initial qualitative ratio of the forces and means of the parties and the coefficient of the degree of fortification equipment of the base camp.

The military conflicts of the last decade are characterized by the wide use of air assets including small - sized and (or) unmanned ones by the warring parties. In modern conditions one of the effective measures to combat them is to increase the accuracy of coordinate information provided to combat (or fire) means. Increasing the accuracy of coordinate information determines: the possibility of non-searching detection and (or) capture of aerial targets by fire means, increasing the survivability of air defense systems due to the reduction of working time (including the time for "radiation") and rapid change of their positions after completing the assigned task. The modern development of science and technology makes it possible to create effective means of air defense to combat existing and promising means of air attack but their development and commissioning requires large costs. In this regard, the issue of improving the characteristics of existing complexes without significant capital investments is gaining relevance. One of the important characteristics of the detection means and tracking of a multi-channel air assets anti- aircraft missile complex is the resolution and accuracy of measuring the angular coordinates of objects. This is due to the fact that modern air defence anti-aircraft missile complex uses information about the angular velocities of the missile-target line and the missile velocity vector when aiming anti-aircraft guided missiles using the proportional approximation method. Therefore, the accuracy of their measurement depends on the features of the missile’s flight trajectory when firing at the target and as a result the probability of its damage. The resolution and accuracy of angular coordinate measurement depends significantly on the characteristics of the antenna system. It is proposed to use their analogues on a modern element base instead of standard multi-channel missile guidance station 9C32 antenna elements in the work . Estimates of the characteristics of the phased antenna array when introducing promising pass-through ferrite phase shifters (in particular the increase in the accuracy of measuring angular coordinates and the range of aerial targets detection) were obtained using mathematical modeling and calculation methods. Obtained ratios allow for an appropriate assessment. The obtained results can be used in the development of proposals for the introduction of modern antenna elements (ferrite phase shifters) into the antenna systems of multi-channel radio equipment of anti-aircraft missile systems.The last decade is characterized by a number of military conflicts, in most episodes of which the achievement of the goal (reconnaissance and (or) defeat of certain targets) by the warring parties is mostly achieved through the use of aircraft, including small and (or) unmanned. The main difference is to obtain the desired results without a direct collision with the enemy ground component of troops (forces). Most of the recommended measures to combat aircraft in modern conditions can be reduced to: the rational construction of battle order (using the air defense separation), the widespread use of covert communications, radio reconnaissance and electronic warfare, the creation of erroneous and camouflage combat (reserve) air defence means positions, automation of transmission and processing of information about the air situation with the use of modern technologies and increase the accuracy of coordinate information provided to combat (or fire) means. Improving the accuracy of coordinate information causes: the possibility of searchless detection and (or) capture of air targets by fire, increasing the survivability of air defense systems by reducing working hours (including time for “radiation”) and rapid change of their positions after the task. Modern algorithms for processing coordinate information provided by air defense systems take into account the errors of primary coordinates measurement by radio engineering, the delay time of information in communication channels and its possible distortion. At the same time, they do not explicitly take into account the influence of topographic errors and orientation errors of radio equipment. In the work with the use of mathematical modelling methods, an assessment of the characteristics of the phased antenna array was carried out with the introduction of a promising pass-through ferrite phase shifter (in particular, an increase in the accuracy of measuring angular coordinates and the range of detection of aerial targets). The obtained ratios allow to make an appropriate assessment. The obtained results can be used when introducing modern ferrite phase shifters to the antenna system of the multi-channel missile guidance station 9С32.
