Hennadii Khudov et al., International Journal of Emerging Trends in Engineering Research, 8(7), July 2020, 3708 - 3715 3708 ABSTRACT The paper proposes the technique of research on the development of radar methods of small air objects detection. The technique includes: using of calculation methods for determining the characteristics of secondary radiation of small air objects in single-position and multi-position reception, using of multiposition radar methods, the methods of mathematical modeling of air object detection processes in radar systems. It is established that using of methods of mathematical (simulation) modeling will allow to conduct statistical experiments, calculate the characteristics of detection of small air objects and compare the effectiveness of different radar methods. Simulation of the process of detecting air objects should be performed using the Monte Carlo method, probability theory and mathematical statistics. Key words : the technique, radar, small air objects, detection, multiposition, mathematic modeling. 1. INTRODUCTION The main trends in the development of air objects at the present stage are due to the introduction of modern technologies and are as follows [1]–[17]: – the improvement of flight and tactical characteristics; – the reduction of radar visibility; – the improvement of on-board electronic equipment and fire means; – the introduction of unmanned control and the latest information technologies. Promising air objects tend to be suitable both for using in large-scale warfare and for use in local armed conflicts, hybrid and cold war [1], [8]–[10], [13]–[17]. Features of radar detection of small air objects are [2], [5]–[6], [8], [18]–[26]: – the short detection range; – finding air objects in the area of illumination from local objects, which requires the inclusion of equipment for protection against passive interference, which, in turn, reduces the detection range; – the small effective scattering surface. It is known that to increase the efficiency of detection of small air objects, a number of organizational and technical measures are used [18]–[26]: – the compaction of the location of the radar in dangerous directions (creation of detection bands of low-altitude and small-sized objects); – using of radars of all frequency bands; – using of radars with the best capabilities (greatest energy potential) and more. 1.1 Problem analysis Information on the monostatic and bistatic effective scattering surface of objects can be obtained by the following methods [18]–[26]: – measurement of the effective scattering surface on special radar landfills, in the field or in radio frequency anechoic chambers using real objects or their large-scale copies; – analytical calculations; – mathematical modeling using numerous methods. Known methods of increasing the detection range of small air objects used in radar are[18]–[26]: – increasing the energy potential of the radar; The Technique of Research on the Development of Radar Methods of Small Air Objects Detection Hennadii Khudov 1 , Serhii Yarosh 2 , Vitalii Savran 3 , Andrii Zvonko 4 , Andrii Shcherba 5 , Pavlo Arkushenko 6 1 Department of Radar Troops Tactic, Ivan Kozhedub Kharkiv National Air Force University, Kharkiv, Ukraine, 2345kh_hg@ukr.net 2 Department of Anti-aircraft Missiles Tactic, Ivan Kozhedub Kharkiv National Air Force University, Kharkiv, Ukraine, syarosh@ukr.net 3 Research center, Military Institute of Taras Shevchenko Kyiv National University, Kyiv, Ukraine, vitaliy-savran@ukr.net 4 Department of Rocket Artillery Armament, Hetman Petro Sahaidachnyi National Army Academy, Lviv, Ukraine, zvonko2008@ukr.net 5 Department of Artillery Facility Complexes and Devices, Hetman Petro Sahaidachnyi National Army Academy, Lviv, Ukraine, 2345kh_hg@ukr.net 6 Department of Metrological Assessments and Examinations, State Research Institute forTesting and Certification of Arms and Military Equipment, Chernigiv, Ukraine, apl1981@ukr.net ISSN 2347 - 3983 Volume 8.
