The military conflicts of the last decade are characterized by the wide use of air assets including small - sized and (or) unmanned ones by the warring parties. In modern conditions one of the effective measures to combat them is to increase the accuracy of coordinate information provided to combat (or fire) means. Increasing the accuracy of coordinate information determines: the possibility of non-searching detection and (or) capture of aerial targets by fire means, increasing the survivability of air defense systems due to the reduction of working time (including the time for "radiation") and rapid change of their positions after completing the assigned task. The modern development of science and technology makes it possible to create effective means of air defense to combat existing and promising means of air attack but their development and commissioning requires large costs. In this regard, the issue of improving the characteristics of existing complexes without significant capital investments is gaining relevance. One of the important characteristics of the detection means and tracking of a multi-channel air assets anti- aircraft missile complex is the resolution and accuracy of measuring the angular coordinates of objects. This is due to the fact that modern air defence anti-aircraft missile complex uses information about the angular velocities of the missile-target line and the missile velocity vector when aiming anti-aircraft guided missiles using the proportional approximation method. Therefore, the accuracy of their measurement depends on the features of the missile’s flight trajectory when firing at the target and as a result the probability of its damage. The resolution and accuracy of angular coordinate measurement depends significantly on the characteristics of the antenna system. It is proposed to use their analogues on a modern element base instead of standard multi-channel missile guidance station 9C32 antenna elements in the work . Estimates of the characteristics of the phased antenna array when introducing promising pass-through ferrite phase shifters (in particular the increase in the accuracy of measuring angular coordinates and the range of aerial targets detection) were obtained using mathematical modeling and calculation methods. Obtained ratios allow for an appropriate assessment. The obtained results can be used in the development of proposals for the introduction of modern antenna elements (ferrite phase shifters) into the antenna systems of multi-channel radio equipment of anti-aircraft missile systems.The last decade is characterized by a number of military conflicts, in most episodes of which the achievement of the goal (reconnaissance and (or) defeat of certain targets) by the warring parties is mostly achieved through the use of aircraft, including small and (or) unmanned. The main difference is to obtain the desired results without a direct collision with the enemy ground component of troops (forces). Most of the recommended measures to combat aircraft in modern conditions can be reduced to: the rational construction of battle order (using the air defense separation), the widespread use of covert communications, radio reconnaissance and electronic warfare, the creation of erroneous and camouflage combat (reserve) air defence means positions, automation of transmission and processing of information about the air situation with the use of modern technologies and increase the accuracy of coordinate information provided to combat (or fire) means. Improving the accuracy of coordinate information causes: the possibility of searchless detection and (or) capture of air targets by fire, increasing the survivability of air defense systems by reducing working hours (including time for “radiation”) and rapid change of their positions after the task. Modern algorithms for processing coordinate information provided by air defense systems take into account the errors of primary coordinates measurement by radio engineering, the delay time of information in communication channels and its possible distortion. At the same time, they do not explicitly take into account the influence of topographic errors and orientation errors of radio equipment. In the work with the use of mathematical modelling methods, an assessment of the characteristics of the phased antenna array was carried out with the introduction of a promising pass-through ferrite phase shifter (in particular, an increase in the accuracy of measuring angular coordinates and the range of detection of aerial targets). The obtained ratios allow to make an appropriate assessment. The obtained results can be used when introducing modern ferrite phase shifters to the antenna system of the multi-channel missile guidance station 9С32.

T his year's Youth Technical Program was amazing, our speaker Garth D'Abreu gave an intensive talk about electromagnetic fields and devices that transmit and receive signals for communication and control. He also spoke about antennas and communication protocols -definitely a lot of food for thought for the young aspiring engineers. The audience participation was great with wonderful questions and comments from the teenagers as well as the preteens.The attendees didn't get much of a break with their hands-on project of building dual band AM/short wave radios from the kits that we supplied. Even though the radios didn't require any soldering (much to the dismay of the HAMS watching from the front of the room!), the kits required a lot of dexterity and good engineering practices of step-by-step assembly coupled with real time debugging. By the end of the workshops most of the radios played and the participant's excitement was evident.Thursday's tour of the exhibition hall was great. We had a large group of parents, grandparents and youths going from booth to booth and getting super talks from the exhibitors about their latest systems and areas of interest. From industry standards to ESD guns, shielding fabrics, field sensing panels, military equipment EMI concerns, antennas, amplifiers, ferrites, gaskets, cables and connectors, everyone had excellent exposure to the world of EMC and what the symposium is all about.I want to take this opportunity to thank the youths, parents, grandparents, Ed Hare (American Radio Relay League -ARRL), Garth D'Abreu (ETS-Lindgren), Aiden Duffy, symposium volunteers, symposium organizers and all of the exhibitors that were so enthusiastic and helped to make this program such a success.Thank you all again and we look forward to next year -it will be really shocking! Editor's Note: Many thanks to Amy Pinchuk and her company InField Scientific for generously donating the dual band AM/short wave radio kits. Amy created and ran the first Youth Program at the 2001 IEEE International Symposium in Montreal and has been active in the program ever since. That's dedication to hundreds of budding engineers over the years!

The article addresses the issues of improving the flight operating safety of aircraft at the landing approach stage and the significance of radio-technical support (including such its component part as lighting equipment) for fulfilling this mission. The state of equipping of the aerodromes of the State Aviation of Ukraine with lighting equipment that would meet compliance with modern requirements was analyzed. The expediency of bringing the characteristics of aviation technology to the requirements of the International Civil Aviation Organization (ICAO) by its equipping with appropriate equipment of domestic and foreign production was confirmed. The issues of the relevance of research on equipping of the aerodromes of the State Aviation of Ukraine with lighting equipment that would meet the minimum requirements of ICAO (International Civil Aviation Organization) were covered. Capabilities of the military-industrial complex of Ukraine in the sphere of development and manufacturing of ground-based lighting facilities for landing using an element base that is employed in the Armed Forces of Ukraine were investigated. The general purpose of the lighting facilities of the aerodrome was given. Critical conditions under which the use of a glide visual indication system that leads to improved flight safety of aircraft at the approach stage were covered and summarized. Varieties of the glide visual indication systems, analogues of which can be used at the airfields of the State Aviation of Ukraine without significant changes in the existing circuits of lighting equipment, were considered. The typical layouts of the glide visual indication systems were given. The requirements for the manufacturing, installation of the wing bar and the algorithm for determining the position of the aircraft relative to the glide by crew were considered.
