(2022 IEEE 2nd Ukrainian Microwave Week (UkrMW), 2022) Шевцов, І. О.; Старокожев, С. В.; Сєріков, А. О.; Дацько, С. В.; Сухоруков, Д. О.; Мачоніс, Т. С.; Коротіч, О. В.; Чумак, В. С.; Білоцерківець, О. Г.
In the presented work, based on the representation of the total flow of range request signals, as well as intentional correlated and uncorrelated interference to a range-finding radio beacon as a Poisson flow, the capacity of both the range-finding beacon range transponder and the short-range radio engineering system as a whole is estimated based on the implementation of the method for extracting synchronous sequences of incoming range interrogation signals in the ground range transponder. It allows on a succession basis to move from the service signal to a requester service and, as a result, increase the throughput of the long -range radio beacon in question.

(PIC S&T, 2022) Свид, І. В.; Обод, І. І.; Воргуль, О. В.; Мальцев, О. С.
In the work presented, a comparative assessment of the accuracy of measuring of aerial objects coordinates was carried out based on the gradual transition from angle-range measuring to range-ranging measurements of the aerial objects coordinates due to the implementation of a synchronous information network of existing range-finding radio beacons. It is shown that the use of rangefinder-rangefinder calculations in radio engineering short-range navigation systems allows increasing the accuracy of estimating the coordinates of aerial objects. This also makes it possible to carry out a transitional transition to interference-protected short-range radio systems.
About the meteor radar modeling problem
(ХНУРЕ, 2024) Ovcharenko, K. S.
The work examines the prospects of not only recovery, but also simultaneous modernization of meteor radars, which are situated in Balakliia Geophysical Complex. They were created in the 70-80s and are now morally and physically obsolete. It seems inevitable that some parameters of meteor radars will change during modernization. The influence of these parameters on the capabilities of meteor radars is considered. The necessity of using mathematical modeling before the meteor radars modernization “in hardware” is substantiated.

Analysis of the Impact of Interference on the Time Position of Signals in Requesting Airspace Observation Systems
(PIC S&T, 2021) Свид, І. В.; Обод, І. І.; Мальцев, О. С.; Воргуль, О. В.; Чумак, В. С.; Сєріков, А. О.
In the presented work, the analysis of the influence of interference and accidental loss of the received response signals due to the final availability factor of the aircraft responder of the airspace surveillance requesting systems on the time position of the decoded signals is carried out. It was shown that a decrease in the readiness factor of an aircraft responder, as well as the probability of detecting single pulses of the used response signals in requesting radar systems for observing the airspace, leads to an increase in both the delay of the output pulses and to an increase in the magnitude of the dispersion. The method of decoding response signals with inter-period pre-processing of response signals is more preferable due to the fact that it has both a shorter delay time and a variance in the estimation of the delay time in comparison with the method of decoding with subsequent inter-period processing of the received signals.
Analysis of the practical measurement of electrical echo parameters in mobile communications
(ХНУРЕ, 2024) Ovcharenko, D. R.
The results of practical measurements of echo signal delays during calls in the networks of mobile operators in Ukraine are presented. It is shown that with the help of electrical echo, facts of call redirection to the network of another operator can be detected, since the echo delay increases. It has been established that the use of a roaming SIM card will not allow simulating a stay in another country if it is registered in the network of the national telecom operator. The use of IP telephony when calling to mobile networks is also clearly determined by the echo delay.

(UKRCON, 2021) Обод, І. І.; Свид, І. В.; Заволодько, Г. Е.; Мальцев, О. С.; Бакуменко, Б. В.; Чумак, В. С.
Secondary Surveillance Radars are widely used in many aspects of users’ information support, such as air object recognition and radio beacon tracking. The study considers a two-channel data transmission system as an SSR model and assesses its relative data capacity subject to intentional (correlated and uncorrelated) and intra-system interference as well as fluctuation (masking effect) noise in the request and response channels. It is shown that the aircraft transponder design built on the principles of a single-channel queuing system with denial of service has a significant impact on Secondary Surveillance Radar relative data capacity and the information security of both the aircraft transponder and the entire Secondary Surveillance Radar.

(SIGMA-NOT Sp. z o.o., 2019) Свид, І. В.; Обод, А. І.; Заволодько, Г. Е.; Melnychuk, I.; Wojcik, W.; Orazalieva, S.; Ziyatbekova, G.
Based on the assessment of the aircraft responders and ground-based radio transponders noise immunity it is shown that the identification “friend-or-foe” systems have a low quality of informational support of the air space control system due to the openness of the interrogation channel and, as a consequence, the possibility of the concerned party to influence on the quality of operation of the aircraft responder due to the radiation of simulated interrogation signals of the simulation steady mode.

(2021) Андрусевич, В. А.; Обод, І. І.
В работе уделено внимание рассмотрению структуры информационного обеспечения пользователей системы контроля воздушного пространства на этапе первичной обработки информации совмещенной радиолокационной системой. Эта система включает первичную и идентификационную системы наблюдения, позволяет рассматривать общую структуру, как единую синхронную сеть информационных систем наблюдения. Такая структура может характеризоваться общим интегральным показателем качества информационного обеспечения системы контроля воздушного пространства. Таким показателем качества может быть вероятность информационного обеспечения, которая является произведением вероятностей правильного обнаружения воздушного объекта первичным радиолокатором и системой идентификации по признаку «свой-чужой» и вероятности сравнения координатной информации первичных радиолокационных систем и идентификационных систем. Такой подход позволяет изменить модель объединения информации первичных радиолокационных систем и идентификационных систем так, чтобы учитывать оценки координат воздушного объекта обеими информационными системами за счет весового сочетание координат воздушных объектов. Расчет координат воздушных объектов по информации первичных радиолокационных систем и идентификационных систем позволяет повысить качество информационного обеспечения лиц, принимающих решения в системе контроля использования воздушного пространства.

(ELNANO, 2019) Стрельницький, О. О.; Свид, І. В.; Обод, І. І.; Мальцев, О. С.; Волощук, О. Б.; Заволодько, Г. Е.
In the presented work, on the basis of the introduced integral indicator of the quality of information support for decision makers in the Air Traffic Control system, the security of the Identification Friend or Foe systems was assessed under the action of intentional simulated interrogation signals flows in the interrogation channel. It is shown that jamming of intentional correlated interference of the required intensity in the interrogation channel allows paralyzing the aircraft responder of Identification Friend or Foe systems, which reduces the likelihood of correct identification of air objects and, as a result, eliminates the accuracy of information in the Air Traffic Control system.

Bandwidth Assessment of Cooperative Surveillance Systems
(AICT, 2019) Обод, І. І.; Свид, І. В.; Мальцев, О. С.; Майстренко, Г. В.; Зубков, О. В.; Заволодько, Г. Е.
Cooperative surveillance systems (СSS), which are formed by secondary surveillance radar (SSR), Multilateration systems (MLAT) and Automatic dependent surveillance (ADS) are the basis of information support of the airspace control system and air traffic control (ATC). СSS represent asynchronous data transmission systems, the capacity of which largely determines the quality of information support of consumers of the airspace control system and ATC. The principle of CSS construction, based on the principle of servicing request signals, predetermined a significant density of intra-system interference and the possibility of the interested party to use aircraft responders by unauthorized request both for receiving data and for paralyzing aircraft responders. In the present paper, on the basis of a brief description of information flows in the request and response channels of CSS, the relative throughput of the aircraft responder under the effect of intrasystem and deliberate correlated and uncorrelated interference in the request channel was evaluated, and an estimate is given of the probability of receiving undistorted data in the response channel under the action of interference, which generally represents the throughput of the CSS.
Basic technologies and techniques ML/AI for improving physical layer security for 5G/6G communications systems
(2023) Tsopa, O.; Dudka, O.; Merzlikin, A.
One of the main features of using the millimeter wave band in the deployment of 5G/6G technologies is that these waves have a narrower range and less ability to penetrate obstacles such as buildings and trees [1,2]. Therefore, millimeter waves require a larger number of communication nodes located closer to each other to ensure network coverage. In addition, due to the high frequency of millimeter waves, they are subject to greater signal scattering and absorption from surfaces such as building walls and other obstacles, which can result in reduced data transmission range. Therefore, it is necessary to consider engineering solutions and technologies of artificial intelligence (IA) and machine learning (ML), which will allow ensuring high-quality communication between communication nodes, taking into account the peculiarities of the millimeter range of radio waves. However, thanks to the high bandwidth of the millimeter wave band, 5G/6G technology can provide high-speed transmission of large amounts of data, enabling new applications and services such as virtual reality (VR), augmented reality (AR), augmented reality (XR), Internet of Things (IoT) and others. Therefore, using the millimeter range of radio waves is an important element of 5G/6G technology that requires specific solutions to ensure reliability and security at the physical level of the network.
