The mathematical formulation of the problem of determining the coordinates of targets in the network of counter-battery radars is formulated. It has been established that the problem of estimating the coordinates of targets in the network of counter-battery radars for an excessive number of estimates of primary coordinates should be considered as a statistical problem. The method for determining the coordinates of the firing positions of roving mortars has been improved, in which, in contrast to the known ones, the coordinates of targets on the flight trajectory are coordinated with space and time and the information is processed by a network of counter-battery radars. The developed simulation mathematical model for determining the coordinates of the firing positions of roving mortars by a network of counter-battery radars. Simulation modeling of the method for determining the coordinates of the firing positions of roving mortars by a network of counter-battery radars has been carried out. It has been established that the use of a network of radars makes it possible to increase the accuracy of determining the coordinates of the firing means on average from 23 % to 71 %, depending on the number of counter-battery radars in the network. It has also been found that the appropriate number of counter-battery warfare radars in the network is three or four. A further increase in the number of counter-battery warfare radars in the network does not lead to a significant increase in the accuracy of determining the coordinates of artillery and mortar firing positions. In carrying out further research, it is necessary to develop a method for the spatial separation of elements of a group of targets and interfering objects by a network of counter-battery warfare radars
The aggressive war against Ukraine makes it clear that the hopes of mankind that future wars will take place in the form of low-intensity conflicts, but rather in the economic, informational spheres without the use of military force, turned out to be in vain. Russia has demonstrated that such seemingly wild actions for the modern civilized world as the seizure of territories, the destruction of cities, attempts to destroy the statehood and self-consciousness of nations will remain relevant as long as autocratic regimes exist and there are no effective international mechanisms that would make any armed aggression impossible. Consequently, the issue of protecting territories and infrastructure in the face of large-scale aggression using the entire list of available types of means of armed struggle will, unfortunately, be relevant in the near future. The article analyzes the recent massive attacks on infrastructure facilities and modern technologies of air defense weapons. As a result of the analysis, possible directions for improving the protection of critical infrastructure facilities were proposed, the main of which is the use of a wide range of systems and complexes of very short-range weapons. In addition, a number of problematic issues and tasks were identified that need to be considered in order to improve the protection of critical infrastructure facilities, the main of which are: safety providing of using the proposed systems directly in populated areas or near them; ensuring the rational use of the resource of weapons, ammunition and other equipment and materiel associated with the functioning of the protection systems of objects; determination of the military formation which will be responsible for infrastructure facilities protecting.
The object of this study is the high level of errors of the first and second kind in the segmentation of images of urbanized areas acquired from space optoelectronic surveillance systems. The method of image segmentation of urbanized areas implies two stages and, unlike known ones: – takes into account each channel of brightness of the color space of the original image; – at the first stage, an ant algorithm is used; – image segmentation at the first stage is reduced to the calculation of the objective function, the areas of movement of ants, and the concentration of pheromone on the routes of ant movement. – at the second stage, the brightness and geometric shape of the elements of objects are taken into account; – contours and geometric primitives are defined in the Hough parameter space; – the objects of interest of the urbanized area in the space of the original image are determined. An experimental study into the segmentation of images of urbanized terrain acquired from space optoelectronic observation systems was carried out based on the ant algorithm and the Hough algorithm. The quality of image segmentation of the urbanized area was assessed. It was found that the error of the first kind when using the improved method of segmentation is reduced by 2.75 %. The error of the second kind is reduced by 3.91 % when using the improved method of segmentation. This reduction became possible due to the use of an improved method of segmenting the image of an urbanized area by the ant algorithm at the first stage. Compared to Canny's algorithm, the error of the first kind decreased by 8.9 %, and the error of the second kind decreased by 11.0 %. Methods for segmenting images of urbanized areas acquired from space optoelectronic surveillance systems can be implemented in software and hardware systems of image processing
Any public events, especially meetings, rallies, demonstrations can turn into riots. Law enforcement agencies are preparing in advance to carry out these activities. In accordance with the governing documents, a special operation is being carried out and groups of operational formation are being allocated to stop the riots. The quality of task performance depends on the timely management of these groups. Operational formation groups are controlled by voice, loudspeakers and radio stations. The equipment of law enforcement personnel during a special operation to stop the riots requires the presence of a protective helmet. It reduces the ability to perceive voice commands. Also, riots are always accompanied by noise, which affects the quality of receiving voice commands by personnel. In accordance with the governing documents, the commanders of subunits and groups of operational formation must have means of communication. However, in conditions of riots, such distribution of communications equipment may be insufficient, which may lead to failure to fulfill the relevant tasks. At the same time, providing each representative of law enforcement agencies with a radio station requires financial costs. The article proposes a mathematical model for determining the required number of means of communication to ensure the fulfillment of the tasks of stopping mass riots. When developing this model, an approach was used to calculate the power of loudspeakers for lumped systems. The developed mathematical model takes into account the specifics of performing tasks during a special operation to stop mass riots and allows you to determine the total number of communications equipment necessary to ensure the management of operational formation groups. The model will help improve the management of operational formation groups and improve the quality of command transmission by commanders to the personnel of these groups.
An important issue of food supply for servicemen with individual needs is the adjustment of diets through the use of protein, vitamin and mineral food components which are functional ingredients of such food, primarily flour based, products as: bread, bakery and flour confectionery (cookies, crackers, gingerbread), fruit and nut energy bars, and “Granola” breakfast cereals. The priority task is to increase the nutritional and biological value of a daily norm for vegetarians and vegans and to balance it in terms of nutritional composition by creating innovative food products with improved consumer properties which contain such functional ingredients as: proteins, fats, carbohydrates in the optimal ratio, rich in vitamins, antioxidants, macro- and microelements. There is rear opportunity to provide hot food in a timely manner in extreme conditions of combac operations which usually solved by snacks and food which could be carried in a pocket. Hence, the actual for the improvement of quality of food supply for the personnel is: composition of dry rations and food rations with products that have convenient packaging and high nutritional, biological and energy value; introducing innovative technologies into the food production process, particularly flour based products; studying the experience of the armies of NATO member states (their rations include flour products: cookies, muffins, biscuits, crackers, bars, nut and fruit pastes with an extended epiry date and high nutritional and biological value); use of the innovative raw ingredients with complex effect, which have a wide range of functional and technological properties that contribute to solve such kind of issues in conflict areas; еxpanding the range of high-quality and socially important food products for Ukrainian military personnel for use in extreme conditions.
