FIELD: radio direction finding, radio engineering systems of automatic determination of angular coordinates of direction vector of propagation of electromagnetic energy. SUBSTANCE: invention refers in particular to single-channel systems with minimal number of immobile omnidirectional antenna elements based on maximal or minimal utilization of properties of standard coupled frequency- or amplitude-modulated radio receivers and can be employed to determine angular coordinates of spatial position of radiation sources with quasi-harmonic change of field intensity in systems of various types and assignment locating positions of objects. EFFECT: increased precision of direction finding. 3 cl, 5 dwg
