METHOD FOR SINGLE-POSITION DETERMINATION OF COORDINATES OF SOURCES OF HIGH-FREQUENCY RADIO WAVES DURING IONOSPHERIC PROPAGATION

摘要

FIELD: radio engineering; radio navigation.;SUBSTANCE: invention is intended for use in radio engineering, radio navigation, as well as in research of ionosphere parameters and increases accuracy of determining coordinates of HF sources from one position. Technical result of invention is achieved due to single target approach, which includes detection and reception on known frequency of multibeam signal by phased antenna array, measurement with required accuracy according to known algorithms of spatial angles of arrival (azimuth, elevation angle) of each mode of received signal and evaluation of their energy parameters, formation of ionosphere model, corrected based on current data of vertical, inclined probing, using data of satellite tomography and magnetometers, as well as a radiophysical model of medium propagation of radio waves of the HF range, solving direct and inverse problems arising in single-position positioning and correction of the ionosphere model.;EFFECT: technical result is higher accuracy of single-position location of radio-frequency source.;1 cl, 3 dwg
