В роботі проведено аналіз впливу руху приймальних елементів системи моніторингу на її функціональні
можливості щодо просторово-часової обробки сигналів від апріорно невідомих стаціонарних джерел
радіовипромінювання (ДРВ) та запропоновано методику визначення координат їх розташування в пасивному
режимі моніторингу із неспрямованим прийомом. Запропонований метод переслідування «ведучий-відомий» на
інтервалі часу моніторингу для однозначного визначення пеленгів на джерела радіовипромінювання в пасивному
режимі під час руху радіоприймачів із апріорно визначеною просторовою конфігурацією.
In this work, an analysis of the influence of the motion of the receiving elements of the monitoring system on its functionality regarding spatial and temporal processing of signals from a priori unknown stationary sources of radio emission has been analyzed, and a method for determining the coordinates of their location in the passive mode of monitoring with non-directional reception is proposed. The proposed method of prosecution is "leading-known" in the interval of monitoring time for unambiguous determination of distances on radio sources in the passive mode when moving radio receivers with a priori defined spatial configuration. Mobile monitoring facilities functionally complement the stationary and provide flexible support for effective radio monitoring during measurements of radio frequency parameters beyond the area of access to them. The tasks of the radio monitoring can be solved by using passive radar systems, which may include not one, but a few spaced radio-controlled receiving modules. A prerequisite for solving the task of determining the coordinate’s sources of radio emission by the system under consideration is the availability of at least three mobile radio receivers modules in the interval of monitoring time. In this system, information received by individual radar detectors is handled jointly. The algorithms considered in the work allow us to determine the coordinates of radio emission sources in the passive mode under conditions of non-directional reception. It should be noted that the implementation of the above algorithms is economically more expedient in comparison with space radio monitoring systems that solve similar technical problems. The efficiency of the application of the dynamical models considered in the work depends not only on the parameters of the radio receiver modules, but also on the signal parameters of the radio emission source. If the phase structure of the signal is not destroyed throughout the spatial-temporal interval of monitoring, then due to the use of a priori known information about the parameters of the movement of radar meters can significantly improve the efficiency of the system in solving the problem.
