FIELD: radio engineering and communications.
SUBSTANCE: invention relates to the radio monitoring systems for both digital and analog communication types VHF-microwave bands radio-frequency sources position (PCRFS) determination, information about which is not available in the database (for example, of the state radio frequency service). Method is based on the desired RFS parameters measuring at one radio control post (RCP) and the same parameters calculation at the point, which location is assumed to be known, at that, measuring its bearing using the RCP with log-periodic rotary antenna system, setting the two virtual posts (VPs) location coordinates in the measured RFS bearing sector at a distance of several angular minutes relative to the RCP, calculating the field strength at the RCP, VP1 and VP2 location, created by each of the q basic radio-electronic facilities (q BREF), known by the applied RCP specified frequency range database and located in the measured bearing sector, establishing the correlation dependence (CD) between the calculated fields strengths on the VP and RCP, making for VP1 and VP2, according to the calculated strengths, position lines q equations in the form of the field strengths q circles equal relationships (CER) (Apollonia circle), independently created by each of the q BREF, making up the baselines between the q CER1 (CERC1) and q CER2 (CERC2) centers equations, as well as the CER1 and CER2 radical axes q equations, and redefining the BREF q coordinates as the CER q radical axes with the corresponding CER q base lines intersection points coordinates, producing the RCP / VP1 and RCP / VP2 pairs calibration parameters (CP) by latitude (CPLT) and longitude (CPLN) as dependences of the difference between the BREF true and calculated q coordinates from the calculated ones. Measuring the desired RFS field intensity on the RCP and calculating by it, using CD, the field strength value on the VP1 and VP2, making up two CER equations (Apollonia circles) for the VP1 / RCP and VP2 / RCP pairs, these strengths radical axis and the CER base line equation. Calculating the desired RFS test coordinates as the CER radical axis with their baseline intersection point coordinates, correcting them by the CD, and then averaging and fixing as the final ones. Increase in the PCRFS determination accuracy is achieved by the additional (n-2) VP coordinates specification.
EFFECT: determination of PCRFS by one radio control post.
