“…They were carried out only to determine the level of support for various political parties that came or were in power. Therefore, in order to conduct a systematic and scientifically sound analysis, the authors have collected all available statistics to determine changes in public opinion regarding the strategic course of the state since 2002, depending on the military-political, economic and social living conditions of the population of Ukraine at the specified period of time [12][13][14][15][16][17]. These data are shown in Table 1.…”

The main purpose of the article is the peculiarities of implementing of the state’s strategic narrative based on the the statistical analysis of the public opinion. The scenarios of the public opinion development are forecasted. The main results are: the graphs of the statistical series of change in public opinion have been constructed; the approximating functions for the trend of change in public opinion have been determined; the parameters of the approximating function have been calculated; a point forecast of the change in public opinion has been made. The main scientific method ia the method of statistical extrapolation. The main results are: to identify the features of the implementation of the strategic narrative of the state system in strategic communications; it is obtained the necessary minimum value of efficiency. This value of efficienct should be achieved by the system of strategic communications, when taking appropriate measures to promote and support of the appropriate course of the state by the population. This result is actually such as in the controlled territory and in the temporarily occupied territories (Donetsk and Luhansk regions, the Crimea). Keywords—strategic narrative, target audience, informational and psychological influence, strategic communications

“…The creation of a small-base multiradar system makes it possible to solve the problem of increasing the energy potential of the radar, increasing the gain of antenna systems using available resources due to the appearance of systemic effects. Combining autonomous radars into a multiradar system provides the emergence of new qualities -systemic effects [3], [13] [31], [33]. In this case, it becomes possible to implement different degrees of coherence of spatially separated positions in the system and combined reception of echo signals.…”

The subject of research in the paper is the problem of choosing a rational number of elements in the structure of a multiradar system of the same type of two-coordinate surveillance radars with mechanical rotation. The purpose of the paper is determination a rational number of multiradar system elements, which will provide an optimal improvement in the quality of detecting air objects according to the cost-effectiveness criterion. To improve the quality of detection of small-sized objects, surveillance radar stations are combined into a spatially separated multiradar system. An assessment of the characteristics of detecting air objects in a multiradar system with a matched signal reception is carried out. The calculations were carried out for systems that consist of a different number of elements. The calculations show that the addition of second radar, regardless of the degree of signal coherence, showed the greatest efficiency in terms of signal-to-noise ratio, the rational number of radars in a multiradar system is no more than four. In a multiradar system of four radars, the threshold signal-to-noise gain can be up to eighteen decibels for a system with coherent signals and up to eleven decibels for a system with incoherent signals. More than four radars are impractical.

“…The possibilities of the existing radar (for example, Figure 1, Figure 2, Figure 3) means for the implementation of radar control and the issuance of radar information with increased requirements for the accuracy of determining the coordinates of the software are somewhat limited. This is due to a number of reasons: radars are exposed to wind loads, weather, icing, temperature and humidity, there is mechanical wear of parts of antenna-rotary devices of locators, which leads to loss of accuracy of coordinate measurement [5]-[8], [16].…”

The subject of study in the paper is to increase the accuracy of determining the coordinates of objects through the use of information ADS-B. Improving accuracy is achieved, inter alia, by adjusting the radar station. The aim is to develop a method of adjusting the radar station using the technology of automatic dependent monitoring ADS-B. Tasks: analysis of known methods of radar alignment, analysis of factors influencing the accuracy of determining the coordinates of air objects, brief analysis of the capabilities of ADS-B technology, development of a method of radar alignment using ADS-B technology. The methods used are: radar methods, methods for determining the coordinates of air objects, methods of mathematical analysis and differential calculus, methods of probability theory and mathematical statistics. The following results were obtained. The main disadvantages of the known methods of alignment of the radar are identified. Factors influencing the accuracy of determining the coordinates of air objects have been identified. The possibility of using the technology of automatic dependent observation to increase the accuracy of determining the coordinates of air objects has been established. A method of adjusting the radar using ADS-B technology has been developed. The main advantages of the proposed method of alignment are determined. The scientific novelty of the results is as follows. Improving the accuracy of alignment of the radar is achieved through the using of ADS-B technology. The advantages of using the proposed method of adjusting the radar are simplification of the alignment process, determination of corrections without removing the radar station from normal operation, the possibility of using as control objects air objects equipped with ADS-B transponders and located in the detection zone of the radar station.
