Выявлено, что существенным недостатком индикаторного канала РСБН является низкая точность определения навигационных параметров (азимута и наклонной дальности летательного аппарата) по сравнению с бортовой аппаратурой. Показано, что в качестве одного из способов повышения точности измерения координат летательного аппарата в индикаторном канале можно использовать траекторную обработку радионавигационной информации. Целью данной обработки является оценка параметров движения летательного аппарата, находящегося в зоне наблюдения РСБН, на основе измерений его мгновенного положения для определения траектории на интервале измерений и прогнозирования его последующего движения. Структура устройства траекторной обработки индикаторного канала РСБН в значительной мере может повторять структуры аналогичных устройств, используемых при обработке радиолокационной информации с учетом особенностей работы индикаторного канала. Разработана структура траекторной обработки и отмечены ее особенности на примере отечественной системы РСБН-4. Проведенное математическое моделирование подтвердило возможность значительного повышения точности измерения координат летательного аппарата по сравнению с существующим индикаторным каналом РСБН-4Н.</p></abstract><trans-abstract xml:lang="en"><p>Features of the indicator channel of the short-range radio navigation systems (for example, the RSBN-4 system) are considered. It was revealed that a significant shortcoming of the indicator channel of the short-range radio navigation is the low accuracy of determining the navigation parameters (azimuth and inclined range of the aircraft) in comparison with on-board equipment. It is shown that one of the possible ways to increase the accuracy of measuring the coordinates of the aircraft in the indicator channel is the use of trajectory processing of radionavigation information whose purpose is to estimate the parameters of the motion of an aircraft in the short-range radio navigation observation zone on the basis of measurements of its instant position for determining the trajectory in the measurement interval and predicting his subsequent movement. The structure of the device for trajectory processing of the indicator channel RSBN can to a great extent repeat the structures of similar devices used in the processing of radar information, taking into account the features of the operation of the indicator channel. The structure of trajectory processing is developed and its features are noted on the example of the system RSBN-4. The performed mathematical modeling confirmed the possibility of a significant increase in the accuracy of the measurement of the coordinates of the aircraft in comparison with the existing indicator channel RSBN-4N.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>траекторная обработка</kwd><kwd>вторичная обработка радионавигационной информации</kwd><kwd>сопровождение целей</kwd><kwd>радиотехническая система ближней навигации</kwd><kwd>индикаторный канал</kwd><kwd>радиомаяк</kwd><kwd>фильтр Калмана</kwd></kwd-group><kwd-group xml:lang="en"><kwd>trajectory processing</kwd><kwd>secondary processing of radionavigation information</kwd><kwd>target tracking</kwd><kwd>short-range navi gation radio system</kwd><kwd>indicator channel</kwd><kwd>radio beacon</kwd><kwd>Kalman filter</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования построения обобщенной структуры устройства траекторной обработки для индикаторного канала радиотехнической системы ближней навигации, приведенные в данной работе, выполнены при поддержке гранта Белорусского республиканского фонда фундаментальных исследований (проект № Т21-071).</funding-statement><funding-statement xml:lang="en">Research on the construction of a generalized structure of a trajectory processing device for the indicator channel of a short-range radio engineering system, presented in this work, was carried out with the support of a grant from the Belarusian Republican Foundation for Fundamental Research (project no.
