Method and algorithms of complex information processing onboard the aircraft for the benefit of definition of accessory of the purposes

Formulation of the problem. On board an aircraft, the solution of situational awareness tasks can be achieved as a result of the creation of an integrated multi-sensor information environment for a complex of onboard equipment, including sources of information that are heterogeneous in terms of construction principles and nature. One of the difficulties in creating such a multi-sensor information environment is the lack of specialized functional software for the on-board equipment complex, which allows processing and combining signals and information from heterogeneous sources, providing an assessment of the coordinate characteristics of targets in the form of phase coordinates of their spatial position and movement, as well as recognition and identification observed targets by characteristic features. To solve this problem, a method and interconnected algorithms for complex information processing have been developed that would allow combining heterogeneous information about targets, taking into account the conditions and methods of obtaining it when solving problems of tracking, recognition and identification of targets. Goal. Describe the method and interrelated algorithms for integrated information processing in the aircraft onboard equipment complex, which provide tracking, recognition and identification of targets based on information received from heterogeneous OBE sources. Results. The method of complex information processing on board the aircraft is described. A set of interrelated algorithms has been developed, including: an algorithm for the complex adaptive assessment of the phase coordinates of the observed target, conditional relative to its trajectory and signal signs obtained from the results of observations of heterogeneous sources; an algorithm for determining the nationality of the observed target, taking into account the assessment of its class / type based on the results of assessing the values of its trajectory and signal characteristics, as well as the conditions for assessing the phase coordinates. Practical significance. The optimization of the processes of a complex adaptive assessment of the phase coordinates of the observed target, conditional with respect to its trajectory and signal signs, and optimization of the decision-making process about the nationality of the observed target, taking into account the assessment of its class / type based on the values of the trajectory and signal signs of this target, obtained from the results of observations of heterogeneous sources. A variant of the practical implementation of the developed method and algorithms in the OBE of the aircraft is proposed.

Designing radiation protection for the scientific equipment complex of the Earth’s remote sensing spacecraft

In the course of operation spacecrafts are exposed to ionizing radiation from outer space. The electronic component base (ECB) used in creating onboard radio-electronic equipment of universal space platforms does not always correspond to the external operating conditions in terms of radiation resistance for some spacecraft orbits due to a number of technical and/or economic reasons. One method to increase the radiation resistance of onboard equipment is to install additional mass protection in the form of screens on the whole equipment or local screens on individual critical radio and electronic components. The article describes the design of additional radiation protection of the geostationary spacecraft scientific equipment complex for adaptation to the radiation conditions of operation in orbits of the “Molniya” type. The solution of the problem involves several preliminary steps, namely: determining the radiation conditions for the spacecraft operation in the target orbit, estimating the local absorbed doses at the locations of the onboard equipment, estimating absorbed doses directly in the electronic component base of the equipment and analyzing the radiation resistance. Designing the radiation complex of scientific equipment was based on the values of the radiation resistance of the equipment and its components, as well as the calculated values of the local absorbed doses in the components

Armament Supplies from the Excavation of the Medieval Ancient Settlement Bolshoe Savrasovo-2 in Leninsky District of Moscow Region

В статье представлены результаты анализа комплекса холодного наступательного вооружения и снаряжения всадника, происходящего из раскопок селища Большое Саврасово-2. Выделены три хронологические группы предметов вооружения – X–XI вв., XII–XIII вв., XV–XVI вв. Находки первых двух периодов (древнерусское время) представлены ручным метательным оружием – наконечниками стрел. Третий период характеризуется увеличением типов и видов воинского снаряжения, что, вероятно, связано с присутствием на поселении дворянина – вотчинника с отрядом вооруженных слуг. The report outlines the results of analysis of cold offensive armament and horseman equipment complex found during the excavation of the ancient settlement Bolshoe Savrasovo-2. There are three chronological groups of armament supplies: the X–XI centuries, the XII–XIII centuries, the XV–XVI centuries. Manual throwing weapon such as arrowheads represent fi ndings of the fi rst and second periods (Old Russian period). During the third period there was expansion in the number of types and sorts of military equipment apparently caused by the presence of a noblemanlandowner with a force of armed servants in the settlement.
