The paper deals with methods and algorithms for increasing the accuracy of unmanned aerial vehicle identification. Accumulation of data on radiation parameters during the session of observation of an object allows to make continuous specification of the made decisions by the set moment of the end of a session of observation the reliability of its identification would be sufficient for acceptance of necessary prompt actions. If to consider a problem of identification taking into account the specified specifics, then in its structure it is necessary to allocate several stages of decision-making depending on volume available for the considered moment of observation of data, conditions of their receiving and processing by the technical means of the information-measuring system. Observation system and control of objects of a sound emission represent difficult sound engineering complexes in which work not only equipment rooms and software, the knowledge base and data, but also intellectual resources of experts are involved. Decisions of different levels in such systems are made not only automatically technical means on the basis of formal algorithms, but also operators, on the basis of the and borrowed experience. Taking into account it is necessary to consider, both bases of creation of formal algorithms of decision-making, and feature of decision-making by the expert for the purpose of clarification of conditions of ensuring the maximum reliability of identification.

Methods for estimating the parameters and states of dynamical systems are an urgent task, the results of which are used in various fields, including processes in technical systems, cosmological and physical research, medical diagnostic systems, economics, finance, biotechnology, ecology and others. Despite significant scientific and practical advances in this area, researchers in many countries around the world continue to search for new methods of assessing the parameters and states of the studied objects and improving existing ones. An example of such methods is digital and optimal filtering, which have been widely used in technical systems since the middle of the last century, in particular, in the processing of financial and economic data, physical experiments and other information technologies for various purposes. The model and algorithms of granular filtering are considered on a practical example - a variant of the problem of global localization of mobile robot (global localization for mobile robots) or the problem of hijacked robot (hijacked robot problem). In the general embodiment, it is to determine the position of the robot according to the data from the sensor. This problem was generally solved by a number of probabilistic methods in the late 1990s and early 2000s. The task is important and finds application in mobile robotics and industry. The tasks of positioning submarines, aircraft, cars, etc. are essentially similar.

The problem of the coordinates determining of the radio emission source in the passive radio monitoring complexes is very relevant, but complex calculation procedure. There are many factors that negatively affect the accuracy of the method. The method proposed in this article will more accurately determine the coordinates of the object. The article considers a mathematical model of space-time objects and a complex radio source. Based on parameterization and coordinate transformation, the hyperbolic system of object position equations is reduced from three to two equations. As a result, reducing the number of iterations and the number of calculations in one iteration of Newton's method are more accurate coordinates of the object. Parameterization quickly determines the new location of the object at the maximum possible speed. Usually airplanes and drones move at a lower speed, so the use of difference-range method and parameterization of hyperboloids allow you to find a new location of the object in one iteration.
Special features of the passive and active radar systems multiplexing
(Osvita Ukrainy, 2015-09) Sineglazov, Viktor; Синєглазов, Віктор Михайлович; Pantyeyev, Roman; Пантєєв, Роман Леонідович; Tkachenko, Valery; Ткаченко, Валерій Миколайович
This paper deals with the unmanned aerial vehicles detection, identification and coordinates calculation approaches that can be used in the complex systems “passive radar-altimeter” and “passive radar-active radar”. The mathematical apparatus of the task solution in the redundancy conditions on the quadratic functional minimization basis is taken into account, justification of the considered method of the coordinates determination is given. Imitating modeling of the coordinates determination is executed.
