The results of developing an intelligent model of radar object images for surveillance radars are presented. The relevance of this work deals with the development of algorithm for automatic processing images of radar objects that provide effective detection of weak true signals due to the accumulation of signal and logical information in the analyzed cell and in its surroundings under interferences. The improvement of air safety tools and the automation of air traffic management processes require effective procedures to process signal information. The issues of more complete use and qualitative improvement of the information-processing capabilities of control systems are also topical, especially in difficult conditions of interfering signals. The basis of this study is the idea of using an intellectual model of radar object images for automatic decision-making on detection and recognition of radar objects, built on the space of semantic features. The main result is optical object recognition, similar to how an expert can easily recognize aerial objects and their types when viewing radar object images. Based on semantic features intelligent model of radar object images has been developed, which makes it possible to effectively detect and classify aerial objects. It is worth noting that the characteristic description of intelligent model of radar object images for point, extended, moving and stationary radar objects is the mathematical description of procedures and relationships at perception and analysis of signals in the form of distinguishing features or properties. As a result, various virtual images of radar object are generated in the form of spatial-semantic and spectral-semantic models. The main features and structural elements of the model are given. It is shown that the advantages of this model are related to the possibility of characteristic description of the radar object images using the algebra of finite predicates.
介绍了一种用于监视雷达的雷达目标图像智能模型的开发结果。这项工作的相关性涉及雷达目标图像自动处理算法的发展,该算法可以有效地检测由于被分析单元及其周围环境中信号和逻辑信息的积累而产生的微弱真实信号。航空安全工具的改进和空中交通管理程序的自动化需要有效的程序来处理信号信息。控制系统的信息处理能力的更全面的使用和质量上的改进问题也是热门话题,特别是在干扰信号的困难条件下。本研究的基础是利用基于语义特征空间的雷达目标图像智能模型对雷达目标的检测和识别进行自动决策。主要结果是光学物体识别,类似于专家在查看雷达物体图像时如何轻松识别空中物体及其类型。建立了基于语义特征的雷达目标图像智能模型,为有效地检测和分类空中目标提供了可能。值得注意的是,对点、扩展、运动和静止雷达目标的雷达目标图像智能模型的特征描述,是以区别特征或属性的形式,对信号感知和分析过程和关系的数学描述。从而以空间语义模型和频谱语义模型的形式生成雷达目标的各种虚拟图像。给出了该模型的主要特征和结构要素。结果表明,该模型的优点与利用有限谓词代数对雷达目标图像进行特征描述的可能性有关。

The study of key encapsulation mechanisms on structured lattices is one of the important directions in modern post-quantum cryptography, as many mechanisms are either already standardized (DSTU 8961:2019 "Skelya") or are promising candidates for standardization (CRYSTALS-Kyber). Estimating the complexity of lattice reduction for cryptographic schemes is an old problem. Asymptotic estimates differ greatly from experimental values, therefore, a number of heuristic methods were developed to solve practical problems. The coreSVP model is a standard means of assessing the security of cryptographic schemes on lattices. The purpose of the work is to analyze the encapsulation mechanisms of DSTU 8961:2019 "Skelya" and CRYSTALS-Kyber keys in the coreSVP model. The analysis was performed using two popular heuristics – GSA (Geometric Series Assumption) and the Chen-Nguyen simulator. The analysis showed that the Chen-Nguyen simulator gives slightly lower estimates than the GSA heuristic. As a result of the analysis, it was found that 8961:2019 The “Skelya” and CRYSTALS-Kyber in the coreSVP model for classical computers have slightly lower than declared security values, but for quantum computers the key encapsulation mechanisms provide the declared security levels. Note that during the analysis, the accuracy of the GSA heuristics and the Chen-Nguyen simulator were analyzed separately. Examples of parameters for which heuristics do not give sufficiently accurate results are given. The performed analysis does not take into account the algebraic structure of lattices used in 8961:2019 "Skelya" and CRYSTALS-Kyber. The inclusion of an algebraic structure in the analysis is a further direction of work. The use of simulators is a promising direction, however, more accurate simulators that take into account the structuring of LWE and NTRU arrays are needed.
结构化晶格上密钥封装机制的研究是现代后量子密码学的重要方向之一,因为许多机制要么已经标准化(DSTU 8961:2019“Skelya”),要么是标准化的有希望的候选者(CRYSTALS-Kyber)。估计密码方案的格约简复杂度是一个老问题。渐近估计与实验值相差很大,因此,开发了许多启发式方法来解决实际问题。coreSVP模型是评估格上密码方案安全性的标准方法。本工作的目的是分析DSTU 8961:2019“Skelya”和CRYSTALS-Kyber密钥在coreSVP模型中的封装机制。分析使用两种流行的启发式方法- GSA(几何级数假设)和Chen-Nguyen模拟器。分析表明,Chen-Nguyen模拟器给出的估计略低于GSA启发式。分析结果发现,经典计算机coreSVP模型中的8961:2019“Skelya”和crystal - kyber的安全值略低于声明的安全值,但对于量子计算机,关键封装机制提供了声明的安全级别。请注意,在分析过程中,分别分析了GSA启发式和Chen-Nguyen模拟器的准确性。给出了启发式不能给出足够准确结果的参数示例。所进行的分析没有考虑到8961:2019“Skelya”和CRYSTALS-Kyber中使用的晶格的代数结构。在分析中加入代数结构是进一步的工作方向。使用模拟器是一个很有前途的方向,然而,需要更精确的模拟器来考虑LWE和NTRU阵列的结构。

The paper considers the features of tracking air objects in existing information networks of radar systems for monitoring airspace. It is shown that the tracking is carried out according to the information of the primary radar surveillance systems, and the secondary radar surveillance systems are used as sources of additional radar information. But the transition to automatic dependent surveillance implies the mandatory use of only request radar surveillance systems. Therefore, the problems of formulating methods and algorithms for tracking air objects based on information from secondary radar surveillance systems are relevant. The specifics of the construction and operation of secondary radar surveillance systems differ significantly from primary radar surveillance systems. The work carried out the synthesis and analysis of the structure of the tracks detector of air objects by interrogating radar systems for monitoring the airspace, namely: a comparative analysis of the quality of identifying the tracks of air objects was carried out; the quality of information support to consumers of the airspace control system with the proposed structure was improved in comparison with the used information processing structure; it is shown that the quality of information support for consumers has more preferable indicators when using the signal processing method during acquisition with subsequent information merging; the influence of the readiness factor of aircraft transponders of interrogative radar systems on the quality of information support for consumers of the airspace control system was evaluated.
本文考虑了现有空域监测雷达系统信息网络中跟踪空中目标的特点。结果表明,跟踪是根据一次雷达监视系统的信息进行的,二次雷达监视系统作为附加雷达信息的来源。但是向自动依赖监视的过渡意味着强制使用仅请求雷达监视系统。因此,制定基于二次雷达监视系统信息的空中目标跟踪方法和算法是相关的问题。二次雷达监视系统的构造和操作细节与一次雷达监视系统有很大不同。通过询问监测空域的雷达系统,对空中物体航迹探测器的结构进行了综合分析,即:对空中物体航迹识别质量进行了对比分析;与现有的信息处理结构相比,该结构提高了对空域管制系统用户的信息支持质量;研究表明,在信息获取过程中采用信号处理方法进行后续信息合并时,消费者信息支持质量具有更优的指标;评价了问询雷达应答器的就绪系数对空域管制系统用户信息保障质量的影响。

An analysis of the current state of power generators of the class E family was carried out. They include classes: inverse E (E-1), with an injection of harmonics – class EM, hybrid classes E/Fn and EFn, including those built based on an active distributed transformer scheme. New developments of such oscillators over the past five years are considered. Significant progress has been made in the development of new feedback schemes. The study of oscillator schemes with power summation and the use of synchronized oscillators is considered. In connection with the appearance of new active devices, circuits using additional active elements – drivers of powerful transistors and the use of two-stroke circuits for the construction of a class E oscillator key are spreading. The proposed classification of oscillators is based on the principle of building an output circuit and a feedback circuit, the morphological table of types is constructed class E oscillators. The principles of operation and characteristics of some new schemes of class E oscillators and their parameters are considered. The trends in the development of class E generators are determined, the main of which is the design of generators for operation in radio engineering systems and matching their parameters with the needs of such systems, as well as in systems of power (industrial) electronics, wireless energy transmission, biomedical and information systems. This is done in accordance with the trend of increasing the oscillator signal parameters while maintaining high efficiency. The variety of power levels, frequencies, and type of performance of class E oscillators is preserved and expanded, in the form of integrated circuits, which allows increasing the parameters of transmitters, sensors, and systems of compatible energy and information transmission.

Stations of radio-acoustic sounding of the atmosphere are a promising means of obtaining information about the altitudinal distribution of meteorological parameters in the Earth's atmosphere used in the process of solving current scientific and applied tasks to ensure aircraft flights, weather forecasting, etc. However, the effectiveness of the existing radio-acoustic means is insufficient, and there are practical needs for development of appropriate prospective structures and algorithms, which will be implemented when constructing specific stations designed to solve actual applied tasks. The article presents a synthesis of the structural diagram of a promising radio-acoustic measuring complex (RAVC) and a complex algorithm of its functioning. It is shown that the process of the RAVC development can be reduced to the development of independent issues. They are as follows: synthesis (selection) of types of sounding radio and acoustic signals, their energy parameters, synthesis of spatial and temporal signal processing algorithms for optimal selection of useful information from signals received against a background of noise, development of complex management algorithms and complex adaptation to external conditions formed by the external environment, as well as development of technical means intended for the implementation of the specified algorithms. According to this task of synthesis (selection) of sounding signals for radio-acoustic systems of sounding the atmosphere in the design process, it should be a joint study of the characteristics and selection of two interdependent types of signals – electromagnetic and acoustic.

The article is devoted to the development and analysis of an avalanche diode generator. The equivalent circuit of the generator is considered and its simplified analysis is carried out. Using the elements of graphic analysis, the conditions of stability of generator oscillations were obtained. The original design of the avalanche diode generator is proposed and considered. A feature of the generator design is the use of a combined oscillating system, which is a three-dimensional resonator in the form of a metal ring made of aluminum alloy placed on a double-sided foil dielectric. Thanks to the top cover made of the same foil dielectric, the oscillating system has a closed nature. The electromagnetic energy supply and output system is made using printed technologies based on a double-sided foil dielectric. The avalanche diode is located in the center of this structure and has a thermal connection with the external radiator. On the one hand, such a decision allowed us to increase significantly the Q-factor of the oscillating system compared to the oscillating system made by the printed method and, at the same time, gave an opportunity to combine the developed auto-generator with other elements of the waveguide path made in the printed version. The developed generator has the possibility of both mechanical, by changing the volume of the resonator with the help of special backlash-free elements, and electronic adjustment, by changing the supply current. The article contains the results of experimental studies of the proposed design of the auto-generator, in particular the dependence of the output power on the frequency of oscillations and on the supply current, as well as the Q factor on the supply current. The research results indicate a fairly high Q-factor of such an oscillating system and, as a result, increased stability of oscillations. In addition, this design to a certain extent improves the overall manufacturability of the design and its material capacity in comparison with the waveguide version.
本文介绍了一种雪崩二极管发生器的研制与分析。考虑了发电机的等效电路,并对其进行了简化分析。利用图形分析的方法,得到了发电机振荡稳定的条件。提出并考虑了雪崩二极管发生器的原始设计。发电机设计的一个特点是使用组合振荡系统,这是一个三维谐振器,其形式是由铝合金制成的金属环,放置在双面箔电介质上。由于顶盖由相同的箔介质制成,振荡系统具有封闭性。采用印刷技术制作了基于双面箔介质的电磁能量供应和输出系统。雪崩二极管位于该结构的中心,并与外部散热器有热连接。一方面,这样的决定使我们能够显着增加振荡系统的q因子,而不是通过印刷方法制作的振荡系统,同时,提供了将开发的自动发生器与印刷版本中制作的波导路径的其他元件相结合的机会。开发的发电机有两种可能性,一种是机械式的,通过特殊的无反冲元件改变谐振器的体积,另一种是电子调节,通过改变电源电流。本文介绍了所提出的自动发电机设计的实验研究结果,特别是输出功率对振荡频率和电源电流的依赖关系,以及Q因子对电源电流的依赖关系。研究结果表明,这种振荡系统具有相当高的q因子,从而提高了振荡的稳定性。此外,与波导版本相比,该设计在一定程度上提高了设计的整体可制造性和材料容量。

Heat-conductive properties of thin heat-conductive polyimide dielectrics have been studied and their thermal resistances have been calculated. Possibility of creating combined printed circuit boards on heat-conductive bases with reduced thermal resistances of polyimide dielectrics from ~ 0.2 to ~ 0.04 °С /W is confirmed. Design parameters and thermal properties of the combined boards with thin polyimide (PI) dielectrics for receivers of concentrated solar radiation are studied. Possibility of providing thermal resistances of PI dielectrics not exceeding 0.43 °С/W has been confirmed. Technical solutions of volumetric light-emitting diode (LED) modules on combined heat-conductive boards, which are 3D-holders-heat sinks, made in the form of single heat-conductive light-reflecting mirrored element, are studied. High thermal characteristics of the modules were achieved due to increase in the area of heat sink holders by more than 2.5 – 3 times compared to flat-type LED modules. Scientific and technical sources were analyzed for selection of modern polyimide materials intended for development and manufacture of combined boards on heat-conductive bases with dielectrics made of polyimide films with increased thermal conductivity up to 0.36 – 0.75 W/(m•K). Potential possibility of creating effective combined printed circuit boards on heat-conductive basis, including those that can be bent, is confirmed using modern industrially manufactured thin heat-conductive PI films with heat-sealable thermoplastic coatings that provide the value of total thermal resistance of boards from 1.5 up to 2.8 °C•cm2/W.

The results of experimental studies of the energy characteristics of the leader transmitter built according to the lamp-pumped organic-dye oscillator-amplifier scheme are presented. When constructing the lidar emitter according to the oscillator-amplifier scheme under conditions of constant pump density, the problem arises of choosing the ratio between the length of the active element of the generator and the length of the active medium of the traveling wave amplifier, which ensures the maximum efficiency of the entire emitter. The main objective of the work was experimental verification of the results of theoretical studies in order to determine the factors influencing the choice of the ratio of the lengths of the active elements of the generator and amplifier based on the organic dye rhodamine 6G with lamp pumping with their limited total length. The results of the experiments confirm the theoretical conclusions that there are optimal ratios of the lengths of the generator and amplifier, at which the radiation energy is maximum. The limiting length of the amplifier and the energy of the emitter, built according to the scheme, the oscillator-amplifier are limited due to an increase in the intensity of the radiation that is amplified along the active element, as well as an increase in the intensity of the amplified noise.
给出了基于灯泵浦有机染料振荡放大器方案的先导发射机能量特性的实验研究结果。在恒定泵浦密度条件下,采用振荡-放大方案构建激光雷达发射器时,需要选择发生器的有源元件长度与行波放大器的有源介质长度的比例,以保证整个发射器的最大效率。本工作的主要目的是对理论研究结果进行实验验证,以确定影响总长度有限的有机染料罗丹明6G灯抽汲发生器和放大器有源元件长度比选择的因素。实验结果证实了理论结论,即存在最佳的发生器和放大器长度比,在该比下辐射能量最大。放大器的极限长度和发射器的能量,根据该方案,由于沿有源元件被放大的辐射强度的增加,以及被放大的噪声强度的增加,振荡放大器受到限制。

Recent advances in quantum technology and the potential that practical quantum computers may become a reality in the future have led to renewed interest in developing cryptographic technologies that are secure against conventional and quantum attacks. Currently, virtually all asymmetric cryptographic schemes in use are threatened by the potential development of powerful quantum computers. Post-quantum cryptography is one of main the ways to combat this threat. Its security is based on the complexity of mathematical problems that are currently considered unsolvable efficiently, even with the help of quantum computers. The security of information systems is ensured through protection against various threats that use system vulnerabilities. Security protocols are the building blocks of secure communication. They implement security mechanisms to provide security services. Security protocols are considered abstract when analyzed, but may have additional vulnerabilities in implementation. This work contains a holistic study of security protocols. Basics of security protocols, taxonomy of attacks on security protocols and their implementation are considered, as well as various methods and models of protocol security analysis. In particular, the differences between information-theoretic and computational security, computational and symbolic models are specified. In addition, an overview of the computational security models for Authenticated Key Exchange (AKE) and Password Authentication Key Exchange (PAKE) protocols is provided. The most important security models for the AKE and PAKE protocols were also described. With the emergence of new technologies that may have different security requirements, as well as with increased opportunities for competition, there is always a need to develop new protocols. Thus, the purpose of this article is to review, classify, analyze, and research the vulnerabilities of information systems from classical, quantum, and special attacks, performed taking into account the forecast regarding the possibilities of attacks on post-quantum cryptographic transformations; studying security assessment models for existing cryptographic protocols, as well as reviewing and benchmarking security models and providing suggestions for protection against existing potential attacks.
量子技术的最新进展以及实用量子计算机在未来可能成为现实的潜力,使人们对开发能够抵御传统和量子攻击的加密技术重新产生了兴趣。目前,几乎所有正在使用的非对称加密方案都受到强大量子计算机潜在发展的威胁。后量子密码学是对抗这种威胁的主要方法之一。它的安全性基于数学问题的复杂性,这些问题目前被认为是无法有效解决的,即使有量子计算机的帮助。通过防范利用系统漏洞的各种威胁,确保信息系统的安全。安全协议是安全通信的基石。它们实现安全机制以提供安全服务。安全协议在分析时被认为是抽象的,但在实现时可能有额外的漏洞。这项工作包含了对安全协议的全面研究。介绍了安全协议的基础知识,安全协议攻击的分类及其实现,以及协议安全分析的各种方法和模型。特别指出了信息理论和计算安全、计算模型和符号模型之间的区别。此外,还概述了认证密钥交换(AKE)和密码认证密钥交换(PAKE)协议的计算安全模型。对AKE和PAKE协议最重要的安全模型也进行了描述。随着可能具有不同安全需求的新技术的出现,以及竞争机会的增加,总是需要开发新的协议。因此,本文的目的是回顾、分类、分析和研究信息系统在经典攻击、量子攻击和特殊攻击中的漏洞,并考虑到对后量子密码转换攻击可能性的预测;研究现有加密协议的安全评估模型,审查和对安全模型进行基准测试,并提供针对现有潜在攻击的保护建议。
