FIELD: radio engineering and communications.
SUBSTANCE: invention relates to radio monitoring systems for determining the coordinates of the location of radio emission sources (CMPRES) of VHF-UHF ranges, both digital and analogue types of communications, information about which is not available in the database (for example, the state radio frequency service). Method for determining the coordinates of radio emission sources (CMPRES) is based on the measurement of the parameters of the desired radio emission source (RES) in a single radio control post (RCP) and the calculation of the same parameters at the points, and their location is assumed to be known. Azimuth on RES is measured by applying RCP with logoperiodic rotary antenna system (LRAS), at a distance of several angular minutes, relative to the RCP, determine the coordinates of the location of j virtual posts (VP) at a distance of several angular minutes from the RCP, form a list of i basic RES (i BRES), based on the data of the RES of the used RCP, in the sector of the tripled mean square deviation of the measured azimuth ϕ, calculate the azimuths ϕ with the RCP and ψ from each of the j VPs to i BRES using the coordinates of their location, establish correlation dependencies of azimuths ψ (KDA) for each of the J pairs of RCP/VP on i of the BRES with j VP from the azimuths ϕ, on them with the RCP, the calibration characteristics (CC) of each pair of RCP/VP in azimuth (CCA), latitude (CCLa) and longitude (CCLo) are determined, for which the coordinates of the test point (TP) are determined in the region of the possible location of the desired RES and the distance from the TP to the RCP and JVP is calculated, construct ixj of difference-relative equations, then change the coordinates of the TP and fix them, as redefined coordinates i of the BRES, when each equation reaches its minimum, obtaining the indicated CCs for all J pairs of RCP/VP, then calculate the azimuth ratios with RCPs on the RES to the corresponding azimuths with j VPs on the RES using the measured azimuths with the RCP and the obtained KDA for each RCP/VP, correct them using CCA, calculate the preliminary coordinates of the RES in the same way as redefining the coordinates of the iBRES, correct the found RES coordinates using CCLa and CCLo, averaged over all J pairs of the RCP/VP and fix them as final CMPRES. In addition, from the measured azimuth φ and coordinates of the location of the RCP form the equation of the azimuthal ray and the TP are moved along it until the minimum of the difference in the ratio in the difference-relative equation of each pair of RCP/VP, and the initial preliminary position coordinates of the TP on this azimuth line are set at the maximum distance from the RCP in accordance with the zone of its electromagnetic accessibility.
EFFECT: definition of CMPRES by a single radio control post (RCP) and the possibility of simplifying the way to determine CMPRES.
