Application of nonlinear dynamics methods for detecting radio signals with frequency-hopping spread spectrum used in communication channels of unmanned aerial vehicles

Gavrishev A.A.; Osipov D.L., Ph.D. of Engineering Sciences, Docent
FSAEI HPE NCFU

The analysis of known approaches for radio frequency detection of communication channels of unmanned aerial vehicles (UAVs) based on the use of radio signals with frequency-hopping spread spectrum (FHSS) is carried out. It is established that in most studies methods, based on energy indicators are mainly used to detect radio signals of this type. It is indicated [21-24] that energy indicators give underestimated indicators for detecting radio signals and, thus, complicate the task of detecting them. As an alternative solution to the problem of detecting radio signals, it is proposed to use well-known methods based on nonlinear dynamics, in particular, the Hurst exponent and BDS-statistics. It is shown that the means of radio-frequency detection of UAV control channels with FHSS, which will be based on the use of the Hurst exponent, will potentially not be able to detect them. It is shown that the means of radio-frequency detection of UAV control channels with FHSS, which will be based on the use of BDS-statistics, will potentially be able to detect them. The results obtained are of rather important practical significance, as they potentially allow, with appropriate adaptation, to perform more effective radio frequency detection of UAVs using radio signals with FHSS.

Gavrishev A.A.
North-Caucasus Federal University

Covert hydroacoustic communication systems based on biosimilar signals are considered on the example of a covert hydroacoustic communication system from [13; 14], which is based on the bionic Morse code. It is shown that in the well-known works [13; 14] does not present bionic Morse code for Russian letters, numerical values ​​and punctuation marks, which potentially narrows the scope of its application. A bionic Morse code has been developed, extending the use of the bionic Morse code from [13; 14] for covert hydroacoustic communication systems, for example, in the prevention and elimination of emergencies at water and underwater objects, the study of potentially dangerous underwater objects and other special tasks, by adding Russian letters, numbers and punctuation marks to it.

Application of KS-entropy for quantitative analysis of civil defense communication systems

Gavrishev A.A.
North-Caucasus Federal University

An experimental analysis of civil defense communication systems using the lower bound of KS-entropy, which is considered as an analog of the structural stealth of transmitted signals, is performed. Among the analyzed models of communication systems, models of communication systems based on chaotic signals have the highest lower bound of KS-entropy and, accordingly, the highest structural stealth. The model of a communication system with simple signals has the lowest lower bound of the KS-entropy and, accordingly, the lowest structural stealth. Model communication systems with noise-like signals has a lower bound of KS-entropy, and, correspondingly, structural stealth, much greater than the model communication systems with simple signals but less than the model of the communication system based on chaotic signals. It is established that communication systems based on chaotic signals are generally more preferable by the criterion of stealth for civil defense communication systems and can potentially find wider application in them.

On the issue of providing imitation protection in systems based on the use of emergency beacons

A.A. Gavrishev
FSAEI HPE NCFU

Systems based on the use of emergency beacons are considered. It is noted that one of their main disadvantages is the availability of transmitted information to an outside observer. It is established that noise-like signals are used in known systems to eliminate this disadvantage. However, most of the well-known works do not pay enough attention to the issues of providing imitation protection of these systems from spoofing the transmitted data. Taking into account the work [2; 13], an imitation protection system based on the use of emergency beacons was developed. A block diagram of the developed imitation protection system is given, and the order of its functioning is described. The developed system, unlike most known systems, can be used to identify and verify the search station for the purpose of transmitting or refusing to transmit the required information to it.

Ufa State Aviation Technical University

In the work forest fires and their classifications are analyzed. Researchers in their works offer various classifications for ground, crown and underground fires. All fires, regardless of their type, are united by one parameter – fire area. The analysis of the literature showed that there is no accurate classification of forest fires of catastrophic class (area of 1000-10000 ha). The classification of forest fires according to the area covered by the fire was developed by method of classification scales construction. The proposed classification includes five main classes of forest fires, each of which is divided into subclasses. In accordance with the developed classification, fires in the Republic of Bashkortostan in September 2018 were analyzed. The developed classification is applied in practice, for example, in land restoration after fires.

The position and width of the working layer of the chemical adsorbent of carbon dioxide in isolating respirators and self-rescuers with the jump of the diameter of the oxygen-containing granules of the product

S.G. Ekhilewskiy, doctor of technical Sciences, associate Professor
Polotsk state University, Republic of Belarus

Expressions for the asymptotics of the mathematical expectation and standard deviation of the coordinate of the elementary act of chemisorption of carbon dioxide in the regenerative cartridge of the insulating breathing apparatus with a circular circuit of the airway in the presence of a jump in the diameter of the granules of the oxygen-containing product are obtained. Increasing the diameter of the granules at the beginning of the regenerative cartridge prevents them from sintering under the action of exothermic heat. A decrease in the diameter of the granules at the end of the cartridge – increases the rate of chemisorption and reduces the dead layer of sorbent. Both increase the efficiency of the protective resource of the device. It is shown that in cartridges with two or more kilograms of oxygen-containing product, even in the presence of a jump in the diameter of the granules, the normal distribution of the carbon dioxide slip has time to form. This allowed us to write a simple equation to determine the increased duration of the protective action of such devices.
