Yaroslav Kozhushko et al., International Journal of Advanced Trends in Computer Science and Engineering, 9(3), May – June 2020, 2981– 2986 2981 ABSTRACT The results of studies of the accuracy of measuring the informative parameters of the sight surface (SS) used for navigation of dynamic objects (DO) in the conditions of their step difference described by a generalized telegraph process are presented. To assess the KENS accuracy potential for this model type image the relations are obtained. The potential KENS positioning accuracy assessment for typical model conditions of DO usage is carried out. The estimates are made for the informative parameter used in radiometric navigation systems, which can be similarly obtained for other types of informative parameters. Key words: Dynamic object, informative parameters, correlation-extreme navigation system, generalized telegraph process, accuracy 1. INTRODUCTION The dynamic object accuracy location, as one of the most important quality indicators, largely depends on the images describing method formed by one or another correlation-extreme navigation system, regardless of the informative parameter type used [1]. For the low-altitude DOs, most frequently used images are of the object against the background type, which are the surface sight images in the form of a step difference informative parameter along the flight direction. To determine the potential accuracy of the radiometric KENS DO the relations are obtained. Numerical evaluations of the DO potential accuracy navigation using a radiometer as an informative sensor and an image of a generalized telegraph process form are performed. 1.1 Problem analysis The SS describing method when assessing the KENS quality functioning, regardless of the informative parameter type, can have a significant impact on the main characteristics of the navigation system, and, first of all, on the accuracy characteristics. There are various ways of presenting images, the choice of which is determined by both the features of the KENS construction and the conditions of their sight. For low-altitude DOs, the most acceptable is the SS representation image along the flight line in the form of a step difference informative parameter described by the generalized telegraph process and taking into account the SS correlation properties [2]. The need for high DO navigation accuracy determines the appropriate studies conduct aimed at assessing the impact of the image presentation method on the KENS functioning quality. The aim of the article is to evaluate the accuracy of measuring informative parameters of the sight surface during low-altitude navigation of dynamic objects equipped with correlation-extreme systems Determination of Accuracy of Low-Altitude Navigation of Dynamic Objects Equipped with Correlation-Extreme Systems Yaroslav Kozhushko 1 , Dmytro Kolomiets 2 , Iryna Tabakova 3 , Iryna Hannoshyna 4 , Nataliia Serdiuk 5 , Tetiana Voichenko 6 1 PhD, Senior Researcher, Department of Air Force Research Center, Kharkiv National University named after Ivan Kozhedub Air Force, Ukraine, oficer2003@ukr.net 2 Senior Lecturer, Department of Navigation and Ship’s Handling, State University of Infrastructure and Technologies, Ukraine 3 PhD, Senior Lecturer, Department of Media Systems and Technologies, Kharkiv National University of Radio Electronics, Ukraine, iryna.tabakova@nure.ua 4 Senior Lecturer, Department of Navigation and Ship’s Handling, State University of Infrastructure and Technologies, Ukraine 5 PhD, Associate Professor, Department of Computer Intelligence Technologies And Systems, Kharkiv National University of Radio Electronics, Ukraine 6 PhD, Associate Professor, Department of Means of Transport Service (Inland Navigation),State University of Infrastructure and Technologies, Ukraine ISSN 2278-3091 Volume 9, No.3, May - June 2020 International Journal of Advanced Trends in Computer Science and Engineering Available Online at http://www.warse.org/IJATCSE/static/pdf/file/ijatcse75932020.pdf https://doi.org/10.30534/ijatcse/2020/75932020
